After dealing with Oliver and watching the endgame credits, the game will load for about .5 seconds and then crash. Tried in windowed and fullscreen, with and without console commands (if I coc'd out of the endgame, my character wouldn't move). From reading other posts, it seems that this is a common occurrence in TTW, in all three endings (I did independent Vegas). I read something that indicated that a levelup triggered by the quest completion may be what's crashing the game, but didn't get a chance to confirm it.
Any help would be appreciated, as I'd like to keep playing and not have to potentially break my game further by COCing out of the Legate's camp.
I can provide specific version information if requested later, I'm not on my home computer.
