Ideas
I did try to look up this problem but the only result I found was a post from 8 years ago and it says solved so I decided to make a new post about it.
In my sims game yesterday I played with a cat in my household (I actually haven't played with pets in forever.) I went to get my cat neutured and when he was accepted in to be seen the vet just stood around doing the same action over and over.
I couldn't cancel the interaction because it said it was in progress. I couldn't leave the lot. I couldn't do anything. My sim literally got stuck there all day and so did my cat and the action never completed. I tried resetting the vet sim and the objects. I tried everything I could think of and even looked at solves for other people previously, and I could not get it to change.
The only way I could get out of it was quitting the game and then starting a whole new game.
I don't have any mods or cc. I repair my game often because unfortunately it needs it.
If you could also please fix every sim going through the trash and knocking it over constantly that would be great :)
