The Sims 4 September 22 Update Autonomy Changes are live in Patch 1.128, and EA has now published the complete list instead of the earlier preview. The update changes how Sims choose social positions, sinks, sleep interruptions, outfits, dancing, gardening and several pack-specific autonomous behaviours.
The Sims 4 September 22 Update Autonomy Changes also overlap with the game’s ongoing freezing and queue work. Some stuck-interaction cases were fixed at the same time, but EA says other freezing and cancelled-action bugs remain under investigation, so autonomy improvements should not be read as a complete fix for every Sim who ignores a command.
The Sims 4 September 22 Update Autonomy Changes in the base game

The Sims 4 September 22 Update Autonomy Changes make several everyday decisions more predictable. Sims should now face one another during conversations, and after using a toilet they should prefer a sink in the same bathroom instead of wandering to a kitchen or distant room.
- Low-energy Sims should stop waking to fill unrelated Fun, Social or Hygiene needs.
- Sims who dislike phones should stop using the Browse Phone idle.
- Sims can choose from several Everyday outfits instead of always selecting the first.
- Sims who dislike gardening should stop autonomously gardening.
- Children should not repeat the swing interaction back-to-back as often.
- Serenades now have a cooldown.
The official breakdown is in EA’s official September 22 patch notes. The Sims 4 September 22 Update Autonomy Changes are largely tuning improvements, but several also fix behaviour that previously looked like broken routing or a stuck queue.
Dancing should be much less obsessive
The Sims 4 September 22 Update Autonomy Changes target several separate reasons Sims danced too often. EA fixed a stereo-related queue problem that could repeatedly add dance interactions, stopped the dance interaction being autonomously queued while a Sim is painting and changed Sims who dislike dancing so they no longer choose it autonomously.
The stereo fix has an important limitation for older saves. EA says that particular repair is not retroactive, but replacing an affected stereo in an existing save may resolve the old state. That makes the object itself worth testing before assuming Patch 1.128 failed.
Relationship autonomy changed in Lovestruck and Growing Together
The Sims 4 September 22 Update Autonomy Changes also rebalance relationships. Lovestruck couple walkbys should no longer fill public venues with repeated couple activities such as sky gazing or kissing, and Relationship Satisfaction should remain unchanged for households while they are inactive.
Romantic Satisfaction is intended to decay more slowly over time. In Growing Together, Sims with awful Compatibility plus Difficult or Distant Family Dynamics should rarely initiate socials, avoid one another more often and end autonomous conversations quickly.
Family Dynamic prompts were tuned too. Strict and Jokesters should occur less frequently, while Distant can now be suggested after malicious interactions or fights, which should make the system better reflect what actually happens between relatives.
Pack-specific autonomy fixes
The Sims 4 September 22 Update Autonomy Changes extend beyond the base game. Get Famous Sims should stop repeatedly admiring autographs, Seasons Sims should make snow angels, snowmen and shovel snow less obsessively, and Ranch Hands should not abandon their jobs to shovel snow on lots they do not own.
High School Years teens who dislike Fitness should stop using Cheer Mats autonomously. Royalty & Legacy Sims with certain Dynasty Ideals also receive fixes for repeated acting scenes or television watching that could interrupt normal tasks.
How this connects to stuck queues and cancelling actions
Some of the most useful The Sims 4 September 22 Update Autonomy Changes are technical rather than visible preferences. Sleep and chat interactions now respond better when the player queues a new command, and several tending interactions can be cancelled through a more consistent queue path.
EA also repaired an idle freeze that could happen after WooHoo when another autonomous interaction was queued. However, the studio explicitly says there are other freezing and interaction-cancellation bugs still being investigated.
If a Sim continues cancelling actions on Patch 1.128, test the exact behaviour without mods and check routing around the target object. The Sims 4 September 22 Update Autonomy Changes reduce several known causes, but they do not make every queue problem the same bug.
