Bug Fixes
Top 5 Most Voted Fixes:
[EA Forums][EA Forums] Extensive updates to ensure that Sims’ eye blinking will now show fully closed eyes for most interactions, see the blog postfor more information on these changes.
[EA Forums] Prom will once again appear on Calendars, and Sims will be able to attend. This fix will ensure it is working for both new and old saves. Alongside this fix, we fixed another issue where Prom goals weren’t able to be completed. (High School Years)
[EA Forums] We fixed an issue where Pet and Horse data was being lost in Premade Households. This issue will no longer occur in new saves. Existing saves where the issue already occurred will not be retroactively corrected. (Cats & Dogs, Horse Ranch)
[EA Forums] We’ve implemented a notable change to how Sims determine who they speak with on a lot. Now, Sims will generally prefer speaking with familiar Sims they already have a good rapport with, and Sims are less likely to engage with strangers spontaneously.
[EA Forums] Animals can be assigned to an Animal Shed after moving the Household to a new lot. They no longer become stuck in Household or Sim Inventory. This is also fixed for saves where the animals were already stuck. (Cottage Living)
Sims Autonomy Improvements
“Sim autonomy” is one of our Quality of Life Team’s key focus areas based on community feedback, and this update delivers on 3 of our top autonomy issues: Sims socializing with strangers, excessive flirting, and Sims using certain objects obsessively. We’ll continue to watch player feedback surrounding Autonomy for future updates.
Base Game
[EA Forums] We’ve addressed the issue where Sims were excessively flirting with each other.
[EA Forums] We’ve heard your feedback and wanted to address Sims using Computers and Phones too often. We’ve added a few new preferences to the Base Game including: Likes Phones, Likes Computers, Dislikes Phones, and Dislikes Computers. If you don’t want your Sims to autonomously use these objects, please give them the “Dislikes Phones” or “Dislikes Computers” Preferences. If you’d like them to use these objects more often, select the appropriate “Likes” Preference.
[EA Forums] If a Sim autonomously uses the Phone, they will receive a cooldown on wanting to do this autonomously again for six Sim hours. This cooldown does not exist for non-active Household Sims, Teen Sims, or Sims who Like Phones. Sims who Dislike Phones (a new Preference we added) will never use them autonomously anymore.
[EA Forums] If a Sim autonomously uses the Computer, they will receive a cooldown on wanting to do this autonomously again for half of a Sim day. This cooldown does not exist for non-active Household Sims, Sims who are Geeks, Sims who Like Computers, or when it is a preferred interaction for Getaways, Clubs, Small Businesses, or Dynasties. Sims who Dislike Computers (a new Preference we added) will never use them autonomously anymore.
[EA Forums] The “Troll teh Forums” Computer Interaction has been added to the same cooldown that is used for other Computer interactions. Sims will also now need Mischief Skill Level 6 or higher to consider this action autonomously unless they have the following Traits: Evil, Childish, Geek, Hot-Headed, Erratic, or Mean (who always have it available). (Base Game)
[EA Forums] If a Sim autonomously destroys a Doll House, it will receive a cooldown on wanting to do this autonomously again for some time. We also made a change so that only Sims with certain Traits (Evil, Hates Children, Mean, Hot-Headed) will ever autonomously decide to destroy a Doll House while Angry. Before this update, this autonomous behavior could occur for any Sim who was feeling Angry or Dazed.
[EA Forums] If a Sim autonomously mixes a drink, they will receive a cooldown on wanting to do this autonomously again for a Sim day for non-NPCs. Previously this would occur frequently for Sims who were Inspired, or Sims with the Bro or Foodie Trait.
[EA Forums] If a Sim autonomously Swims, they will receive a cooldown on wanting to do this autonomously again for some time. This cooldown does not exist for non-active Household Sims, on Pool Venues, during Pool Party, or Birthday Party events, when Swimming is a preferred interaction for Getaways, Clubs, or Small Businesses, or if the Sim is a Merfolk or PlantSim.
[EA Forums] If a Sim autonomously plays the Violin, they will receive a cooldown on wanting to do this autonomously again for a Sim day. This cooldown does not exist for non-active Household Sims, for Sims who are Music Lovers, Sims who Like Violins, or when it is a preferred interaction for Getaways, Clubs, Small Businesses, or Dynasties.
[EA Forums] If a Sim autonomously plays the Guitar, they will receive a cooldown on wanting to do this autonomously again for a Sim day. This cooldown does not exist for non-active Household Sims, for Sims who are Music Lovers, Sims who Like Guitars, or when it is a preferred interaction for Getaways, Clubs, Small Businesses, or Dynasties.
[EA Forums] If a Sim autonomously plays Chess, they will receive a cooldown on wanting to do this autonomously again for a Sim day. This is for non-NPCs only, and not applicable during Clubs or Getaways involving Chess.
[EA Forums] We’ve added a cooldown for Sims dancing while on a lot that the Sim owns. Sims who Like Dancing, Dance Machine Trait Sims, and certain situations will not receive this cooldown. This cooldown is not for non-active Household Sims. This cooldown will disappear when Sims move lots in case they are going to a lot where they want to dance.
[EA Forums] We’re reducing how often a Sim considers turning on the Radio. Sims with the Music Lover trait will consider listening to music more often than other Sims.
[EA Forums] Though practically a staple of Sim culture (I’m being cheeky), we’ve added a cooldown for autonomous Push-Ups, Sit-Ups, and Stretches. Now, only Sims who are Energized at the Gym Venue or Sims with the Active trait will consider doing this autonomously.
[EA Forums] We’ve added a cooldown for Foodie Sims watching Culinary Training Videos on the Television where they won’t do this autonomously for two days after doing it.
[EA Forums] If a Child Sim autonomously uses the Space Ship Jungle Gym, they will receive a cooldown on wanting to do this autonomously again for a Sim day. This cooldown does not exist for non-active Household Sims or when it is a preferred interaction for Getaways, Clubs, or Small Businesses. Leaving the current lot also removes the cooldown.
[EA Forums] If a Sim autonomously plays with the Lump of Clay, they will receive a cooldown on wanting to do this autonomously again for a while. This cooldown does not occur for Creative Sims or Sims who Like Pottery.
Discover University
[EA Forums] If a Sim autonomously plays with the Soccer Ball they will receive a cooldown on wanting to do this autonomously again for a while. This cooldown does not occur for Sims who Like Fitness or non-Household Sims.
Cottage Living
[EA Forums] If a Sim autonomously does Cross-Stitch, they will receive a cooldown on wanting to do this autonomously again for some time. This cooldown does not exist for Sims who Like Cross-Stitching or when it is a preferred interaction for a Club.
Lovestruck
[EA Forums] Sims will no longer consider playing Who’s Up Party Games while in the middle of writing a Book on the Computer.
Adventure Awaits
[EA Forums] If a Sim autonomously plays with the Paper Airplane, they will receive a cooldown on wanting to do this autonomously again for a while. This cooldown does not occur for Sims who Like Papercrafting.
Spa Day
[EA Forums] If a Sim autonomously uses the Yoga Mat, they will receive a cooldown on wanting to do this autonomously again right away. This cooldown does not exist for High Maintenance Sims or Sims who Like Wellness. (Sims must be Wellness Skill Level 2 to Autonomously use a Yoga Mat – previously and still.) The cooldown is removed when leaving the lot, and when it’s the preferred interaction for Getaways, Clubs or Small Businesses.
Movie Hangout
[EA Forums] A cooldown has been added to the Popcorn Popper so that after it has been used by a Sim that Sim will not want to immediately use it again for some time.
Pet & Animal Fixes
With two of our Top Community Issues being around animals and pets, we fixed a few other bugs also in this category to provide a better overall experience with these systems.
[EA Forums] Animals in the Animal Shed, Chicken Coop, Mini Goats, and Sheep will no longer be multiplied. This was happening when these animals were placed into a Sim inventory, then back in the world, and after that the Sims moved their Household. (Cottage Living, Horse Ranch)
General Bug Fixes
We addressed a handful of other important issues that were quickly rising with player reports, particularly problematic in gameplay, or easy to fix.
Base Game
Sims with the Unflirty Trait will no longer get the ick when hugged.
Placing a painting on the wall and then returning it to the Sim’s Inventory will no longer result in a Simulation error.
Seasons
[EA Forums] Flowers will no longer get stuck midair while crafting a Flower Arrangement.
For Rent
[EA Forums] The “Do Inspection and Maintenance” interaction is now available on applicable working and broken objects in a Tenant Household for Landlord Sims. This should function both during Maintenance events and outside of them for Landlord Sims.
Life & Death
We’ve adjusted design elements on some of our swatches for the Ornate Mystery Rug which were ** concerning to some players.
Royalty & Legacy
[EA Forums] There was an issue where the updated Family Tree could cause wrong connections and overlapping which has now been fixed.
[EA Forums] We fixed a crash that could occur when resuming the game after deleting the Capp Household in Ondarion.
[EA Forums] Ondarion’s Verdemar lot is no longer reversed.
Parenthood
Child and Teen Sims who grew up in the same Household but weren’t related could get the Super Sibling relationship, despite not being related and then could later romance each other. Because we didn’t want to prevent stories where children could have possibly been in the same Household at one point while not related and end up in a relationship, we decided to fix this by renaming the relationships to Childhood Besties and Childhood Frenemy.
StrangerVille
There should no longer be a Script Call Fail error when the Plant Containment Cell is on the lot and the player tries to place other objects.
CAS & Build Mode Tagging Updates
We had the opportunity to address a large swath of simpler tagging bugs, making CAS and Build Mode sorting more accurate overall. Here are related issues we fixed:

Sycee of the Prosperous Moon, Right Side Up Gnome, and Bob the Butler Fancy Sculpture have been removed from their previous category and are now sorted under Decorations > Sculptures.

We updated a large amount of love seats and benches to properly be identified as “Benches” for lot requirements when placed.

We’ve adjusted the Lovestruck Beard swatches to display in the correct order.
(ymBottom_EP16Jeans) will now appear as a Masculine Fashion Choice in CAS filters.

<Modder changelog>
Fixed Issue
Change Log
(ymBottom_EP16Jeans) will now appear as a Masculine Fashion Choice in CAS filters. (Lovestruck)
Added filter tag to asset (ymBottom_EP16Jeans).
(yfTop_SP08TeeBoatNeck_GradientPink) no longer sorts as Yellow in CAS filters. (Backyard Stuff)
Removed filter tag from asset (yfTop_SP08TeeBoatNeck_GradientPink).
Updated the swatch color for (yfMakeupLipstick_EF28GlossyLips_RedRuby) to appear more accurate.
Updated swatch icon color for asset (yfMakeupLipstick_EF28GlossyLips_RedRuby).
All Makeup that was in the Everyday Category has been added to both Hot and Cold Weather Outfit Category as a sorting option. This will make it easier than ever to do your makeup for these categories (since the options were previously hidden in many cases).
Added Hot and Cold Weather Tags to the base prototypes for all makeup assets. Removed Hot and Cold Weather Tags on a few specific assets that also did not have Everyday Category tags.
Animals can be assigned to an Animal Shed after moving the Household to a new lot. They no longer become stuck in Household or Sim Inventory. This is also fixed for saves where the animals were already stuck.Animals being unable to be assigned to the Animal Shed after moving was blocking another, older bug where Animals would become unresponsive after being assigned to the Animal Shed after moving. Since we fixed the first one, we also fixed this one alongside it.
Created a boolean tuning field ‘allow_transfer_out_of_hh_inventory’ that, when enabled, will allow an object in the HH inventory that cannot be directly placed in-world (eg. livestock animals) to be properly slotted to an in-world object. Enabled this boolean in the tuning for the loot action that slots livestock animals to their sheds.Modified the function that removes the animal shed object to return early if the shed is currently in the HH inventory (so the animal shed will not get erroneously unregistered from the animal service when moving HH)
Animals in the Animal Shed, Chicken Coop, Mini Goats, and Sheep will no longer be multiplied. This was happening when these animals were placed into a Sim inventory, then back in the world, and after that the Sims moved their Household.
Stopped tracking objects in the lost and found service if their location is currently in the Household Inventory (because they cannot be lost if they are in the HH inv).Properly set the livestock animals’ owner ID field in the python code after they are assigned to a shed (since livestock animals cannot be placed in-world they were bypassing the logic that normally sets that field, causing the Sim to not own them anymore after moving HH)
Sims will no longer consider playing Thumbs Up or the WooHoo Card Game while in the middle of writing a book on the computer.
Adding tests to autonomousSimPicker_TriviaBox_ThumbsUp_PlayWith and autonomousSimPicker_TriviaBox_WooWho_PlayWith to ensure Sims who are writing on the computer are not considered
Flowers will now longer get stuck midair while crafting a Flower Arrangement.
Set the Create Target Name of the arrangementTable_Passive Animation Element to be the in-progress craft arrangement. Also updated the VFX participant type in the outcome of the flowerArrangingTable_Arrange interaction to be CreatedObject instead of CraftingObject.
If a Child Sim autonomously uses the Space Ship Jungle Gym they will receive a cooldown on wanting to do this autonomously again for a Sim day. This cooldown does not exist for non-active Household Sims or when it is a preferred interaction for Getaways, Clubs, or Small Businesses. Leaving the current lot also removes the cooldown.
Adding a cooldown to autonomously running JungleGymBoat_Play and JungleGymRocketShip_Play
If a Sim autonomously uses the Yoga Mat they will receive a cooldown on wanting to do this autonomously again right away. This cooldown does not exist for High Maintenance Sims or Sims who Like Wellness. (Sims must be Level 2 to Autonomously use a Yogo mat – previously and still.) The cooldown is removed when leaving the lot, and when its the preferred interaction for Getaways, Clubs or Small Businesses.
Adding a cooldown to autonomously running si_Yoga_Practice and Yoga_Routine
We’ve heard your feedback and wanted to address Sims using Computers and Phones too often. When considering how to fix this, we felt there were stories to tell around Sims who can be a little obsessed about Phones and Computers and also Sims who do NOT like them and never want to use them! Because of that, we’ve added a few new preferences to the Base Game. These Include: Likes Phones, Likes Computers, Dislikes Phones, and Dislikes Computers. As their names imply, these new Preferences are particularly important now when determining how your Sim will (or won’t) engage with Computers and Phones. If you don’t want your Sims to autonomously use these objects, please give them the “Dislikes Phones” or “Dislikes Computers” Preferences. If you want them to be obsessed… you know what to do. Please enjoy!
Adding new Traits for phone and computer preferences. These are tested on the aptly named Phone and Computer super interactions.
In addition to the new Computer-related Preferences, if a Sim autonomously uses the Computer they will receive a cooldown on wanting to do this autonomously again for half of a Sim day. This cooldown does not exist for non-active Household Sims, for Sims who are Geeks, Sims who Like Computers, or when it is a preferred interaction for Getaways, Clubs, Small Businesses, or Dynasties. Sims who Dislike Computers (a new Preference we added) will never use them autonomously anymore.

We’ve added a cooldown for Sims autonomously turning on the stereo to listen to music.
Adding a cooldown to autonomously running Stereo_AutonomousPickChannel as well as adding dancing cooldowns.
If a Sim autonomously destroys a Doll House it will receive a cooldown on wanting to do this autonomously again for some time. We also made a change so that only Sims with certain Traits (Evil, Hates Children, Mean Hot-Headed) will ever autonomously decide to destroy a Doll House while Angry. Before this update, this autonomous behavior could occur for any Sim who was feeling Angry or Dazed.

We’ve added a cooldown for Sims dancing while on a lot that the Sim owns. Sims who Like Dancing, Dance Machine Trait Sims, and certain situations will not receive this cooldown.

Placing a painting on the wall and then returning it to the Sim’s inventory will no longer result in a Simulation error.
Objects duplicated between world and inventory will be discarded from inventory on load
• We did extensive updates to ensure that Sims’ eye blinking will now show fully closed eyes for most interactions.• High-impact animations—such as blinking in CAS, sleep loops, kissing, and looking down at a phone—were given extra focus to ensure eyes fully close.• In some rare cases, some eye sets may experience slight over-blinking due to their shape—which was preferred to consistent under-blinking across most eye shapes.• We did a lot of work to provide the best visual experience for eyes closing with upper and lower eyelashes slotted for a Sim:• The most noticeable interactions for players received special attention to minimize any clashing between eyelashes.• High-impact animations—such as blinking in CAS, sleep loops, kissing, and looking down at a phone—were given extra focus to ensure eyelashes don’t clash.• Upper and lower eyelash clashes may still occur with certain eye shapes and less noticeable interactions. We did our best to minimize this issue.• Lower lashes now move along with the lower eyelid.Unusual brow movements during some sleep loops will be fixed. This was tied to certain mood animations partially being played while a Sim was sleeping.
The Cantina High Top Tables object now has a price of $550 Simoleons, rather than $0.
Updated price in tuning
Prom will once again appear on Calendars and Sims will be able to attend. This issue was occurring in old saves created prior to a previous Prom-related fix, but this fix will ensure it is working for both new and old saves.
When scheduling prom, we were testing for any early graduate Sims, but the Tests would always fail on older saves. Moved those tests to when prom is run.
We fixed an issue where Prom goals weren’t able to be completed.
Updated score multiplier test to return a default value instead of throwing an error when running on simless events.
We’ve implemented a notable change to how Sims determine who they speak with on a lot. With these changes, we hope to make Sims feel a bit smarter when it comes to socialization. Now, Sims will generally prefer speaking with familiar Sims they already have a good rapport with, and Sims are less likely to engage with strangers spontaneously. On top of this, they’ll also factor in distance before choosing a Sim to talk to. Our intention is that it’ll be less likely for stranger Sims to push into a conversation between friends but not outright remove Sims wanting to get to know one another. Likewise, we didn’t want Sims charging across the lot to start a conversation, and Sims should no longer be psychically targeting another Sim for socialization over great distances. Paired together, we feel this update makes Sim socialization feel less disruptive, more appropriate, and generally much more enjoyable.
Adding a new aggregate interaction (aggregate_SocialObservation_Chat) to determine the proper Sim to run SocialPickerSI on.
We fixed an issue where Pet and Horse data was being lost in Premade Households. This will no longer occur in fresh saves. However, if this occurred in an old Save, it will still be occurring in that instance.
Re-exported premade household info with pets in game.
