I joined a friend's game, he was on Act 3, he gave me some stuff and then left the game, i left the game after awhile and exited the game. When I logged back on, I was stuck on Act 3 with HIS story progression. My story progession is on Act 2. I tried to join an Act 2 game and did the same thing, but when i log bock in, i am still stuck on Act 3.
