Seleya (yeah, they stole my name, lol) the VH was revived, but never shown in the alive list. It never shown in chat that they were revived either. Still showed them in the dead list.
This showed for multiple people and only one of the last three people (2 mafia and survivor) alive was able to vote for them because they obviously didn't have a button if they didn't show up.
This happened to me on Steam.
