Thanks a lot! I'm going to check it out.
Found something interesting when replying the route to see if there was something that could be recreated.
I got this ingame error some days before the game crashed
Image 'day139_movie_b_room_pregnant' not found.
it did not crash until after the wedding night just like last time.
Not sure if it has any connection to the error but still a missing image can have a ripple effect :)
