Are you supposed to be unable to attack the first night after becoming Assassin via the Mastermind’s skill? It says nothing about this in the skill’s description.
You are suppose to be able to attack that night.
The bug was probably not discovered as it is very unlikely that MM will turn into assasian, as most games end before this point.
Yeah, it caused me to lose the game. During the night, it showed that I had become the Assassin, but neither of the two skillboxes was displayed at the bottom of the screen.
