OMG thanks Adel for feedback. I've been yearning for people to check it for days.
1. doctors claiming day 1, and cross-protecting for the rest of the game
That's why I placed a Scum Group Roleblock.
2. the vampire claiming in twilight to create a pre-mature lylo
I honestly did not see this. OK, I should make the Vampire protectable.
Some questions:
1. What do you mean by swinginess?
2. When I ran the worst case for town, it had three mislynches. If that's two small, then adding two more vanillas should solve it right?
3. Hmmm... what if I make it a Traitor instead of Vampire (scum alignment at start, unknown to the rest of the town, but unNKable.)
