The problem was that I knew all along that the mafia members were online. So, I assumed that my mistakes had inadvertently revealed two of their identities.
Besides, the Master was already known to us because of the role check, so there was no need to worry so much.))) So, his reveal actually helped the town. In my opinion, it would have been better to restart the game with a new role distribution than to do it this way: "Gentlemen of the mafia, I messed up badly, so now the town is allowed to adapt as much as it wants."
