I don't know why but it's done this to me before and now after all of my hard work and everything I have been logged out and had to restart and I've decided this time I'm not going to undownloaded the game because it's pissing me off that every time it updates or there's an update available it restarts my game either fix it or don't update the game anymore cuz there's no point in updating the game if it restarts you from the beginning
