I was playing a Coven All Any game in which I was the Necromancer. There was a Janitor in the game who was cleaning regularly. Normally, when a person is killed, you will see a symbol associated with their role (in the Necromancer's case, a skull) upon the flip. When they are cleaned you will see "We could not determine %name%'s role." and a dice block symbol. For most cases when people were cleaned and stoned, everything worked as normal. However, when I was killed and cleaned, I saw the message "We could not determine Webber's role" as normal, but there was a skull underneath it instead of the usual dice block. I checked the chat log and the graveyard, and I was definitely cleaned.
Unfortunately I have no screenshot of this, as I was caught off guard by the bug and didn't react in time.
