The Sims 4's September 22 patch is live on all platforms, bringing 95+ bug fixes and a handful of systemic overhauls that target some of the game's most persistent annoyances. Autonomy, family dynamics, infant behavior, university tracking, and console stability all got attention in this one.
Here is what changed and what to keep an eye on before you load your save.
Autonomy fixes finally address the dancing problem
If your Sims have spent the last several months breaking into spontaneous dance routines at every opportunity, this patch is for you. The team addressed multiple issues that caused Sims to dance far too often, and the Dislike Dancing trait now actually works: Sims with it will stop dancing when a song they dislike plays and will no longer start on their own. The particularly ridiculous case of Sims dancing while painting has also been removed.
Repetitive autonomous TV watching got a pass in some situations as well, though the notes are less specific about exactly which scenarios were targeted.
These are the kinds of autonomy tweaks that quietly change how a play session feels. If you have been manually canceling dance actions every few Sim-minutes, this patch should make a noticeable difference. Recent updates have been chipping away at similar irritations, like the phone notification overhaul from late June that let you mute your Sim's phone for the first time.
Relationships and family dynamics rebalanced
Family Dynamics have been retuned so that commonly triggered events happen less often, while rarer dynamics now have more chances to fire. The goal is more variety in how family stories play out across a save.
Relationship Satisfaction from the Lovestruck pack also got adjustments. The big one here is a considerable reduction to relationship decay, which should make it easier to maintain relationships without constant micromanagement. Players who felt punished for switching between households or stepping away from a couple for a few in-game days may find things more forgiving now.
Infant and university fixes
Infants are getting several fixes, with the most notable targeting a recurring issue where infants would incorrectly pop out of their cribs. The notes do not detail every infant bug addressed, but crib behavior has been a consistent source of frustration since infants launched.
Discover University's rotational gameplay is also getting a targeted fix: degree progress checks can now account for Sims outside your currently active household. If you play rotationally and have had university students lose track of their degrees when you switched away, this should help.
Console stability gets a structural rework
One of the top console crash causes was tied to controller navigation and memory usage. Rather than patching around it, the team reworked how controller navigation grids are handled entirely. Additional crash work is planned for October, and the team noted that higher-risk fixes are going through dedicated test charters and engineering reviews before release.
This is worth watching if you play on PlayStation or Xbox and have been dealing with intermittent crashes, especially in menus or build mode.
Free content and mod warnings
The update also includes free new content for the Base Game, first teased last month by the Sims Community. Exact items are not detailed in the patch notes themselves.
As with any major update, mods and custom content are expected to break. Check that your mod creators have released updated versions before re-enabling your Mods folder. EA has an official guide to mod maintenance and save backups if you want to be thorough about it.
The update is available now through the EA App, Steam, Epic Games, and Origin on PC and Mac, and through your console's update system on PS4, PS5, Xbox One, and Xbox Series X/S. On Mac the download is around 580MB.
