Just recently decided to get into co-op missions with a friend. Basically, every time I either make a mission, or download it, when he tries to join it give him 1 of 2 errors that have been happening. One of them is; He joins, picks a position on a team and we ready up and hit play. Upon loading in, Ill get to the mission overview where i'm on the map and his game will crash, every. single. time. He's not on a shitty pc either. The other error is "you cannot play/edit this mission blah blah blah" and it says CST_R_TOWER, and he is unable to play. I know this is a lot to read but help would be hugely appreciated, Thanks.
