I am playing the Doppleganger mission and I sneak through to the boat where I need to kill a guy and take his suit. I am not using cheat codes or anything. Once I sneak up and kill him, I can hear his body getting thrown in the water, and the screen is black - but the game ALWAYS crashes at that point, and I can`t seem to pass it. Has anyone else had this problem. It is very frustrating.
