I spent over 10 hours playing yesterday on the PC for my fucking game to be reset to the day before??? FUCK!

cause of steam? never heard of that happening, that sucks.

dont abruptly shut down the game or steam with alt f4 like some people, steam needs to sync up files to the cloud.
if you dont want this you can choose somewhere to use local game files for loading instead

+1, if it ever asks you local or cloud's file choose local since it'll obviously be the good one

Don't play it off steam.
It's trash.
