The Sims 4 September 22 Update Patch Notes are now live, confirming Patch 1.128 as one of the larger quality-of-life updates of 2026. The final build numbers are PC 1.128.90.1030, Mac 1.128.90.1230 and Console 2.39, with more than 95 fixes alongside new free Create a Sim and Build/Buy content.
The Sims 4 September 22 Update Patch Notes also clarify an important point for anyone dealing with freezing or disappearing interactions: EA fixed several specific causes, but it has not declared the wider problem solved. The studio says other freezing and cancelled-interaction bugs are still being investigated, so players should separate confirmed fixes from issues that remain open.

EA published the full first-party details in EA’s official September 22 patch notes. The Sims 4 September 22 Update Patch Notes are much broader than the pre-release Laundry List because the live notes include the final crash list, autonomy tuning, save fixes, Build Mode corrections and technical notes for modders.
What Patch 1.128 fixed for freezing and interactions
The Sims 4 September 22 Update Patch Notes include several targeted fixes for Sims becoming stuck. EA repaired one case where time and Sims could freeze while environmental animations continued because two Sims were competing for the same interaction position. It also changed queue behaviour for sleep and chat interactions, including group chats, and adjusted several tending interactions that could remain stuck.
Another fixed case involved Sims becoming idle after WooHoo when an autonomous interaction was queued at the wrong point. Infant interactions also received changes intended to stop some crib and playmat states from cancelling or blocking actions after a reload.
Those fixes do not mean every report is closed. The Sims 4 September 22 Update Patch Notes explicitly say other Sims Freezing and interaction-cancellation bugs are still being investigated. That makes the distinction important for players who install Patch 1.128 and still see the same broad symptom.
Crash and stability fixes in Patch 1.128
The Sims 4 September 22 Update Patch Notes contain a substantial stability section. EA fixed a rare Mac rendering crash, a console gamepad-directionality crash, a Sim-model rendering crash in CAS or Live Mode, a SimService crash, a path-planning crash and a crash that could occur when moving from Build Mode to Manage Worlds.
The patch also addresses several asserts involving pools inside contour walls, particle effects, entering Create a Sim through the Simology Panel and heavy VFX scenes. High School Years received a Social Bunny fix for a crash that could occur after moving between tabs and closing the app. Enchanted by Nature received two additional stability fixes.
EA also says its highest automated crash report during this investigation was linked to outdated mod files. That does not prove that every crash is mod-related, but it is a strong reason to test Patch 1.128 without an old Mods folder before assuming the base game is responsible.
Autonomy, relationships and everyday behaviour
The Sims 4 September 22 Update Patch Notes put autonomy at the centre of the release. Sims should now face one another more reliably during conversations, prefer a sink in the same bathroom after using a toilet, stop waking from low energy to perform unrelated needs actions and use more than the first Everyday outfit when several are configured.
The patch also reduces repeated autonomous dancing, tones down some couple activities in public venues, adds a cooldown to serenades and changes behaviour for Sims who dislike gardening, dancing or phones. Relationship Satisfaction in inactive Lovestruck households should remain unchanged while they are not being played, and Romantic Satisfaction should decay more slowly.
Growing Together Family Dynamics received balancing changes as well. Difficult or Distant relatives with awful compatibility should initiate fewer socials, while Strict and Jokesters dynamics should appear less frequently and Distant can now be offered after malicious interactions or fights.
Collectibles, saves and other notable fixes
One long-running world-spawn problem is finally addressed. The Sims 4 September 22 Update Patch Notes say Rocks, Dig Sites, Frog Logs and Wild Plants can now account for time that passes while the Sim is away from the active lot, allowing them to respawn instead of repeatedly resetting their timers when the area loads.
Save behaviour also changed. Using Save and Exit should no longer create a separate save slot instead of versioning the active save, and restoring an Auto-Save before making a manual save should no longer create an unnamed save or overwrite the wrong slot. AutoSave and save-reminder timers now reset independently.
Other fixes cover Gallery venue placement, Build Mode wall-pattern categories, roof-trim clipping, the Eyedropper tool, career phone interactions, exercise commands, infant travel states and several pack-specific issues. For the complete official list, the EA notes remain the source of record.
Free content added with the update
The Sims 4 September 22 Update Patch Notes also include a free base-game content drop focused on children and toddlers. The Build/Buy additions include the Crayon Chronicle notebook clutter, Look What I Made! Frame, Family Game Night Favorites, Junior Artist’s Paint Palette, Make-Believe Wall Mural, Bright Blocks Playroom Chair and Table, plus the Dino Dive Tank aquarium.
Children receive new clothing and hair options, including a sweatshirt, polo shirt, khaki shorts, sequin top, ruffled blouse, jeans with lace detail, one new ponytail and four adult hairstyles converted for children. Toddlers receive a T-shirt, colourful glasses and a denim dress. A new Styled Room, Styled Looks and Maxis Gallery household are part of the drop too.
The Sims 4 September 22 Update Patch Notes therefore cover far more than bug repairs. Patch 1.128 combines new free content with stability work and a large autonomy pass, while leaving a small number of important technical investigations open. The Sims 4 September 22 Update Patch Notes are now the correct live reference for those changes.
