Hi coffeist and yes, this mod has recieved alot of work since first version. However, I was a bit clumsy when releasing last version 2.2 as alot of players have this problem with not being able to go back in the menu. There are no quick fixes for this problem as its hardcoded in the game, at the moment I'm finishing up my COOP mission Operation Jolly. I will take a weeks time to fix the bugs once this mission has been released.
