I was Body Guard killed by Mafia + Jan on night 2. After Day 3 and upon the start of night 3, I noticed a couple of Game Messages that do not belong to Body Guard let alone a dead one.
I got:
"You Dragged your target off to jail!"[white text]
"You have slain a town member so you can't attack again" [green text]

While rather minor and harmless, thought you should know!
