I've just found myself having the same problem, 15 hours of gameplay down the drain. I've tried rebooting the game and the console (Xbox One). I think the only option left is to uninstall and reinstall but with my rubbish wifi that's going to take hours, I'll give an update in about 12 hours or so to let you know if it has worked or not.

@ajashley Update: Didnt work, back to the start for me.
