At this point, I'll take any plan that moves the game forward. I'm going to switch over to post-game analysis.
I think this game is an interesting experiment (and I've run my share of experimental rules), but players here are too cautious to handle this low level of information and too contrarian to meet the majority-vote execution requirement. It's hard enough to get a majority under normal conditions (and even with multi-vote it doesn't often happen), but the lack of information has put players into a "wait and see" mode that will inevitably lead to a Scum win by default.
It's like my Wheel of Life mafia. Players could foresee that cautious play would lead to an everyone-loses stalemate. And yet they still played cautiously. So everyone lost.
