Not a real bug...but the whole hostility with the NCR after playing through FO3 story needs fixing if it isn't in TTW 2.0
Not sure if you want to fix exploits, but there's one where you can get infinite experience by repeating a conversation option with Angela Williams after completing There Stands The Grass. Another one happens when you side with the Powder Gangers and you can repeat a dialog option for infinite experience and leather armor with Chet at the general store.
There is a bug involving a slave child over at the fort. Eventually, the child just spawns outside the walls and you can't return her teddy bear.
