I am playing Assassin's Creed on an xbox 360. My problem is that i completed all of the citizens, view points, and investigations in damascus, for the second assassination there, and i had to go to work. So i got the feather from the guy at the bureau, let the game save, and turned it off. i came back and started it back up, and all of the save citizen points are vigilantes or scholars, as they should be, i still have the extra sync bars from completing objectives, none of the view points are on the map and it wont let me do them, and none of the investigations are there, but it wont let me do the assassination! i cant even find it. it says my status is 0/6 investigations, 0/10 citizens saved, and 0/9 view points, but the guy at the burea acknowledges that i have the feather already, and wont do anything for me except tell me to get on with it. so im stuck. i have tried everything short of erasing the game from my hardrive and starting over, which i really dont want to do. any suggestions?
