When I enter either Blind Eye Summit East or West, there is a bug with the graphics which eventually causes the game to crash. The graphics do not completely draw in either one of the East or West zones and I am unable to finish this section because of it. Is this a known bug? are the fixes available, or do I just have to scrap this game and find another?

Please, if you have any information, or can point me in the right direction, it would be greatly appreciated.
