One third of the townies had alt win condition, and two gave the townies vigs to shoot scum with (one was -required- to shoot scum and also required to defend themselves from an nk to get it), and only one of those townies left the game after achieving the win. Although I'm not sure how good vigs are in this setup >_>;
Of course, the one that left the game was practically guaranteed to achieve theirs fairly early in, rendering them effectively neutral ITP and not town, and both the vigs were unlikely to fulfill their roles (albiet me fulfilling mine would have been crazy town benefit)
The cop thing would have been okay if they didn't get false positives ON BOTH KINDS OF RESULTS, since cop is a crazy powerful role and watering it down is normally okay.
