[HSY] All highschool students reset during class

All sims including the playable and NPC students will glitch into standing position almost immediately after sitting down for class as well as sitting down for lunch. They do not just get up out of the chair; there is no animation they just reset completely. I try commanding them back into the seat but as soon as they sit down they glitch right back out of it. The NPCs will try sitting back down over and over again until class is concluded. For lunch it’s the same thing the Sim will be sitting down while eating or chatting and they glitch into standing position and all queues are reset. I've removed all mods, all CC, removed all saves and started a new save file, repaired the game but still the same problem. I’ve also noticed sometimes there is quite a bit of lag while on the school lot and sometimes queues do not appear after commanding them or take a long time to appear.

Both SAMSAMIL and I have answered your questions in our initial posts.

My game is a fresh save that I started back in Spring 2026, 100% mod and CC free. I tried repairing my Spring 2026 save and I tried generating a fresh, vanilla sims 4 folder to test if the issue is persists - it does. I also tried repairing the game with the fresh, vanilla sims 4 folder - still does not fix the issue.

SAMSAMIL said they removed all mods/cc, tested a new save, repaired the game, and re-tested with a fresh, vanilla sims 4 folder as well.

The issue remained for us when we generated fresh vanilla sims 4 folders.

i just seem to be having my sim just standing around a lot when i am trying to get her to complete an action

This is the only bug report i could find for HSY:

[HSY] All highschool students reset during class | EA Forums - 13774055 Does this sound like your problem?

Yes, this sounds like my issue.

For me, i completely uninstalled and reinstalled everything, i wiped the entire Sims 4 Folder so EA could give me a brand new one when I start up the game. No mods, no cc, no nothing and still the glitch persists. Mine is at the high school all Sims reset after trying to sit down for class or lunch. It happens over and over and over again I have tried absolutely everything and nothing is working.
