I always have last exceptions in my sims 4 folder, usually 2 or 3. I make sure to delete them before restarting my game. Is this the same for everyone? I am a totally vanilla player.
I get these too. Like you, usually about two or three and not all the time. I think they might occur when I have sims suddenly jump out of an interaction. I have a few mods but not many and mostly tuning.
