I'll keep this short. I'm in sloan, the game has become laggy because some deathclaw corpse has clipped into the ground and is spastically shaking around. I try to fast travel away, the game crashes. I leave the immediate vicinity so the game isn't laggy anymore, it crashes before I can fast travel. I try again and manage to fast travel (to another destination) after I've left the buggy area, and it crashes again.

I know there's no point in ranting about how disappointed I am in the bugginess of this game (Even though it's been out for 7 months). So I'll just shut up and hope you fix this crap.

EDIT: Oh, and I can't reload the saves the most recent save after the game crashes. Nice.
