Don’t recommend playing co-op on same screen.

Me and my cousin started this game at the same time and got up to level 56. We saved and pressed exit and when we game back it restarted all of his progress up to 45 and lost all of his weapons and armor he earned. We are really upset due to the amount of time and progress we got juts for his stuff so not save EVEN THOUGH we pressed “save progress and exit”
