My Sim keeps Disappearing
I go to play on my household of one sim and she's gone, in the bottom left it says shes fine and the only option I have when I click on her is 'Care For Self' and she's not on my lot. I tried to reset her but it said 'Sim Not Found'. This has happened almost five times and each time I have to evict my sim and move her back in again from the gallery (she was a starter sim so I didn't really lose any valuable relationships or anything). It has happened on and off when I send her to community lots as well. I have a lot of CC in my game if that helps.
