Who knows what's true and what's not in a game of deceipt?

Writing them out is a good way to go, as it frees up a lynch vote, though would affect the balance of the game. If a werewolf goes AWOL, their class could be trasferred to another player - but anyone who had seen that person previously would have to be informed of the change, or you'd get a wolf in sheep's clothing. Likewise if a seer went AWOL, their power and also results from previous seeings they had done would need to be transferred. Even transferring a werewolf has a problem, as you have no way of knowing if a seer told a human that they were a seer and for that human to suddenly become a werewolf and know who to attack...

If a seer/guardian/werewolf does not select a target, then it could be chosen at random. Werewolves can try to lie low or simply miss the dealine - perhaps they should be forced to attack by the maddening blood lust and their target chosen at random?
