playing this on ps3, i cannot go nowhere near camp forlorn hope as it slows done to the point of being unplayable and freezes, the surrounding hills around the camp are no out of bounds as the game will crash, this is a serious piss take, anyone else ha dthe same issue in that area of the game?

Yep.
Not so bad for me at Forlorn Hope but pretty bad at Golf, for some reason.
