I just wanted to throw my name in for another player that is experiencing this proble. PS3 Disc version, after doing every other side mission possible and have been waiting 2 weeks for a fix. I am just going to trade my game in. This is unexceptable and I will be thinking twice about buying another game from you guys.
Also stuck on this quest. Cutscene will not activate. Complete game breaking bug. I will warn anyone else playing on ps3 when you get to the canada quest line go directly from quest to quest and do not look around because it will break the game
