The fact that there were both silencers and plotters made that impossible. It was like trying to solve a three variable equation system with just two equations. Just can't be done.And regarding the final vote count: did ANYONE used that "information" to try and deduct who the plotters were?
Then again maybe that was the idea? Baddie plotters normally can't use their trait until the endgame or when they are up for lynch or they will be kill when found out.
If you remember the second werenuts game, where players were teamed up two and two and only the last vote from a pair counted, that was similar in that the vote count made no sense compared to what people voted in the thread at first but after 5-6 nights it was possible to deduce who was together (well, rather it would have been possible if the GM hadn't messed up and allowed some pairs to break the rules governing how they could vote).
