The modified rules hint at a secret communication twist. It could be something that helps one (or more) of the following groups:
• scum e.g. scum can talk during the Day
• town e.g. masons can communicate
• third parties (if we have any) e.g. there could be an additional fraction, or a competition between PFKs (like in Evil Dead mafia)
Or it could be a red herring, though that’s unlikely because in that case sachertorte probably wouldn’t have re-posted the rules.
This type of twist can make things a lot more complicated (and interesting), because if some subset of players gets to secretly communicate, then they might be able to pull off more elaborate strategies. So I’ll be on the lookout for (IOW, even more paranoid about) people working together, and perfect information slips.
Hero, be nice to Almost Human; I think AH and I are the only two women in this whole town 
Personally, I agree with her about mislynches. Let’s not get too hung up on them. The exact number is too hard to predict anyway. It seems like larger games usually have two night kills, so we might have a Serial Killer or a Vigilante. In that case, we’ll probably have even fewer mislynches. And if we have a good/lucky doctor, we might get an extra mislynch.
