Yesterday I was playing campaign and I had just got to the mission part in Kaffarov where you play as blackburn and investigate. I got off because it was late hoping to continue the mission later, but Today when I try to play It does not give me the option to continue my campaign. Every time I click on Campaign in the main menu It just gives me the option to start a new campaign and make me choose my difficulty. Anyone have any help for me? Also I play on Xbox 360
