My sims either won't follow a command (just stand there) or they "do" it without actually moving. For example, they will go to sleep without getting into bed. I've linked to a video to better explain...
Ideas
Did you never use mods or remove them ?
Have you tried a game repair yet ? It sounds a bit like an issue that was fixed a while ago.
I removed the mods and deleted the local cache file; is there another way to repair?
yes, click on the three dots in ea app and choose repair.
