Crashing trying to enter The Excavation map at end of Arastas

Whenever I try to load the map, the game white screens and crashes. Upon reloading the character, game crashes and closes. Reloading into most recent instance or town instead loads the character, but retrying entering excavation crashes again. Tried verifying integrity of files through steam and didnt help.

Problem was solved by completely uninstalling and reinstalling the game as the game wouldnt let it's files be moved by Steam.
