I'm having the EXACT same issue!! A friend and I were playing multiplayer (shared, Xbox One) and then the game crashed booting us both. Logged back in from last save (load pic looked like I was on a Zipline last, but the game crashed while I was in my fort), and I'm getting an all white screen. Health, food, water not moving either. I can't even give up to at least move myself elsewhere. I'm stuck!
Anyone heard anything as of late??
