The Sims 4 September 22 Crash Fixes are now confirmed in the live Patch 1.128 notes, with EA targeting crashes across Mac, console, Create a Sim, Live Mode, navigation, Build Mode and several pack-specific situations. The patch is PC 1.128.90.1030, Mac 1.128.90.1230 and Console 2.39.
The Sims 4 September 22 Crash Fixes also include an unusually useful warning for mod users. During its investigation, EA says its top automated crash report was being caused by a conflict with outdated mod files, so a post-patch crash should be tested without old mods before it is treated as a new base-game regression.

The Sims 4 September 22 Crash Fixes cover both crashes EA could reproduce and high-volume failures found through automated reports. The list is not a promise that every possible crash has disappeared, but it does identify several concrete failure points repaired in Patch 1.128.
- A rare Mac rendering crash during longer play sessions.
- A console crash linked to gamepad directionality.
- A crash while rendering Sim models in CAS or Live Mode.
- A SimService crash affecting a smaller group of players.
- A defensive fix in path planning and navmesh handling.
- A crash while moving from Build Mode to Manage Worlds.
EA provides the full technical list in EA’s official September 22 patch notes. The Sims 4 September 22 Crash Fixes should be read alongside the wider patch notes because several freezes and stuck interactions were repaired without being classified as crashes.
Base-game asserts and rendering problems
The Sims 4 September 22 Crash Fixes include several asserts that could destabilise a session. EA changed a case involving a swimming pool built inside a contour wall, another involving particle visual effects and another that could occur when entering Create a Sim from the Simology Panel.
A separate fix covers scenes with a large number of visual effects on screen at once, with EA using many occult Sims as an example of the type of situation that could trigger the problem. These fixes are technical safeguards rather than new gameplay features, but they can make heavily populated or visually busy saves more reliable.
Social Bunny crash is fixed
High School Years is part of The Sims 4 September 22 Crash Fixes. EA fixed an assert that could sometimes become a crash inside Social Bunny after a player moved between tabs and then closed the app.
That means the specific Social Bunny tab-switching crash listed in the September 22 notes should no longer be treated as an active known bug after updating. If Social Bunny still crashes on Patch 1.128, reproduce it without mods and report the new steps rather than assuming it is the same resolved issue.
Enchanted by Nature stability changes
The Sims 4 September 22 Crash Fixes also touch Enchanted by Nature. EA addressed a crash affecting a small number of players in connection with Luck and an assert that could occur when Zhaleh Amani attempted to WooHoo in a bush in certain saves.
These are narrow fixes, which is useful when troubleshooting. A general crash in an Enchanted by Nature save is not automatically the same bug simply because the pack is installed.
Why outdated mods matter after Patch 1.128
The most important diagnostic detail in The Sims 4 September 22 Crash Fixes is EA’s statement that an outdated-mod conflict produced its largest automated crash signal. The patch also includes a base-game-side change for a mod that was corrupting memory for a moderate number of players.
This does not make mods the explanation for every crash. Instead, it gives players a clean test order: move the Mods folder out, delete localthumbcache.package, start a fresh test save and reproduce the same action. If the crash disappears, return updated files gradually rather than dropping the entire old Mods folder back in.
If the crash still occurs with a clean user folder, repair the game through your platform, confirm the Patch 1.128 version number and test the same steps again before reinstalling. Keeping the test controlled makes The Sims 4 September 22 Crash Fixes much easier to verify.
Crashing is different from freezing
The Sims 4 September 22 Crash Fixes should not be confused with the separate freezing work in the same update. A crash closes or terminates the game, while the freezing reports EA is still investigating can leave the world visible with Sims or time stuck.
Patch 1.128 fixed several specific freezing and queue problems, but EA explicitly says other cases remain under investigation. If your game stays open but Sims stop responding, use the dedicated Sims 4 Freezing guide rather than treating it as one of the confirmed crash fixes.
The Sims 4 September 22 Crash Fixes are a meaningful stability pass, especially for players affected by the named scenarios. The safest post-patch setup remains a current game build, a backed-up save and only mods that have been checked against Patch 1.128.
