Anytime I am playing the game and someone dies I try to go back a day, OR MORE, and the further back the date I pick, the higher the percentage of a chance of crash. I was once or twice able to load "yesterday", but the game crashed every time I picked a day before "yesterday," A.K.A. the previous cycle. It's even crashing my entire computer a portion of the time. The most recent crashed actually locked my computer and I don't even have a password. It's happened on or around day 14, day 30-somethings, and day 40-somethings. When the game crashes a split second of sound loops, and the screen goes black or it freezes on the options menu in game play.
