So...firstly this haven't happen a lot...Maybe once in a week or something so I didn't pay attention...But, lately it started to happen every time. I thought it is maybe some bug because of my mods to the game (calendar and players) but I re-installed the game completely and before doing any mods wanted to play some fast career. But, it blocked again! Simply, picture gets frozen at one moment and I can't do anything with my computer. So I need to force restart (push up button)! This happens every day when I play. Also, all weeks before get invalid!
