@ El Cremoso. Alcuin didn't post the link of the game because it is Anonymous. If you wanted a rollback to cancel that player's illegal move, you should have sent a PM to Oli ASAP after you noticed it, within the next phase.
Since Oli's the only one that can fix it, there's no use in typing the gameID on a Public Forum, unless you goal was to destroy the gunboat and reveal the name of 2 players out of the 5 still alive.
@Alcuin. You are perfectly right. The matter was already debated here:
threadID=21887Next time it would be better you send a PM to Oli as the thing happen, because rollbacking 1 turn is not simple but Oli usually does it, rolling back 2 turns may be too complex.
