I have the same problem at the moment, i play everytime in singleplayer "mode" but after mission 7 i get the message that i'm not so far in singleplayer and go back to the last safe in singleplayer, then i start in the prolog mission again... My skills and items still there, but then i'm with (60%) back to the prolog. So i can't play mission 8. What is this for a bug ? Can someone help me ?!
