I will also say a big public Sorry! to Russia... I cocked up and used an old version of my spreadsheet and saw bulletproof, when it should have been death proof. Had this not happened I suspect he may have been in with a chance to win...
I don't think you should feel bad about it -- you accidentally did him a favour. We saw the message because he was lynched; if we hadn't seen the message the reaction from Town to a failed lynch is almost invariably to try again. Whatever suspicion they had is confirmed by the witch trial failing to kill the target the first time around, and they burn anyone who won't drown
Instead it was only because that messsage popped up that I tried very hard to keep him in the game for as long as possible, which worked pretty well. He lasted longer than me lol.
