[S] Stuck on Select Season for several unrelated interaction (1.113.288/2.09)

The same thing happens to me every time I log out I get the seasons screen, as if I was making a new game... and then also when I go to a community lot with only one sim, the whole household appears on the lot and also if I want to send them home it doesn't let me... I don't have a mod or cc, but this happened when I met a strange man with a hat who also changed all my settings... And if I did all that and fixed it 3 times, and if in a new game that doesn't happen, how can I make my main game go back to normal?
