Chaqa's last-minute switch to Bunny really makes me think he knew it was going to tie. I think he could have done that regardless of damo's alignment, based on bozo's analysis that keeping town!damo around for a myslinch today would win them the game. And although I think it is likely that damo is the JOAT for the reasons you mentioned in your above post, I also don't think it's that much of a stretch for Chaqa to have activated it early when his team (or at least Vecna) wasn't around to keep him from doing so.
But, I agree we need to avoid any possibility of a tie, so ##vote damo
