Yet nothing concrete. If the game was broken we'd know who was who. As it happens, there's plenty of doubt still bubbling away.
And we have a list of potential roles that are included, but not a clue who might be who. And character claiming is basically role claiming. I mean, yes, this game is run rather differently from how I've played it before, but I wouldn't say it is a bad thing. I'd certainly wait until after the game was finished before providing feedback.
