That's what I said. Hence Day2 PoE being 3 people not 1.
I don't know anything about what, if anything, is written in the EV project about this setup.
But the way I see it Town has a 100% win rate after a Day1 Vanilla mislynch. I suppose Mafia have no choice but to YOLO and try to block or kill the Watcher N1, so they're not guaranteed to lose.
