I am used to playing sims, changing households often. I notice that for example I played Sim 1 then after 2 days (real days), I will play 2. When I got back to play sim 1, I notice that he became fatter, this also happens to other household that I am playing. What is going on? Is this normal. They dont have SLOB or couch potato trait and some are unemployed while other have a job but eventually if I dont play them they get fat. Is this normal?
