Forum:Beat the game and...

So I beat the game on my hunter, first play through and everything goes well, the quest gets checked off at completed and then the game crashed before I can do anything. I think no big deal, try again, beat him again, this time with hardly any sniper rounds, game crashes again!

I dont have any mods, nor have I done antying to tamper with the game in any way. Can anyone help me out please or do I have to restart the game pretty much?
