I just came across a glitch. I was innocent and I was killed by the random mafia killer, and I think other people were, too. Someone had a suitcase with papers and it said what it would say if a mafia would have the papers, but they were innocent. I knew I was innocent and he handed them to me and they said the same thing. I'm guessing the game assigned some people mafia, but it told them they were innocent. I also could not check to see if players were innocent when I clicked them so I was definitely innocent.
