Bug:
I was Amnesiac and remembered VH the night the last (and only) Vampire died, I was actually one of two Amnesiacs to remember VH, but they remembered a night before me, when the Vampire wasn't dead and therefore when he died turned Vigilante. I'm guessing that because I remembered the night the Vampire died I actually stayed VH until the end of the game, and never turned Vigilante even though there weren't any left (Town won).
