I think there's nothing wrong with the zombies mechanically. I think them reverting back to their previous alignment on death is a bit soft, but it's not like it breaks the game in any way. Different is not bad
And behaviorally... I mean, they were really cocky which kind of pissed me off, and it felt, to me, like they were relatively town-siding for most of the game and that got worse after I died, so I felt very justified in putting some heat on em. I was also pretty pissed about the circumstances of my death, and the utter lack of coordination of my team, so that might have colored my mood a bit. But getting pissed off by your enemies is the lifeblood of mafia, so good job, zombies. If The Ghost Of York's Spite didn't return from the grave you might have had a chance of cooperating with the other chucklefucks on my team
Also, just so everyone knows; I was not one of the girls here in this instance. York and Fuji maintain a very cordial friendship, and their is no bad blood as the result of this game
