[Possible Spoilers]

Ive completed 84% of the game(27/33 missions) and just completed my first mission for greaves(i killed addi mbantwe), ive got back to Mosate Selao as there is a single mission marked on my map. Unfortunately, when i get there the guard at the door wont let me into the building so i cant get the next mission,im stuck. Anyone else had this problem?

Sorry mate, didnt think as im frustrated by the bugs in this game, ive added a spoiler warning now. Luckily it was a very minor one, after all, who doesnt end up dead in this

BTW, to get around this bug is it possible to use a friends game save, so i can carry on or are game saves locked to the profile(360) they were created in?
