Well you did have a 50% chance of losing the lynch, so it wasn't that much of a RNG.
Though, had you not been on the lynch, you would have won for sure:
Placa dies : 2 Guests - 1 Corrupt.
Sanae is Lynched : 1 Guest - 1 Corrupt or No one is lynched : 2 Guest - 1 Corrupt (Then the Police kill 1 House Guest, making it 1 Guest - 1 Corrupt).
Sooo yeah :/
Np, your lack of activity at the very end didn't effect the game negatively, so I don't care.
