I can play online. This is your game, not my Xbox. Same exact thing is happening to my wife on her Xbox One S. So, you have 2 different Xbox models running your game & neither one can load a previously saved game. Are you saying this is not a known issue? Reinstalling the entire game is a weak solution, if it’s a solution at all.
And has it been reported before? Yeah, it has and they had to reinstall the entire game to fix Can't Load a single player offline game
Like I said, a WEAK solution. Do you employ anyone to run down these issues, or is it always the ol’ ‘reinstall it, cuz you got nothing better to do with your time’?
EDIT: After going through ALL your steps, STILL can’t access my game. Matter of fact I can’t even start a new single player game now. It kicks me to the Xbox dashboard at 99% load into a new single-player game!!! Refund?
