I don’t think you were being hit inside the market house, what I was saying is that I think it’s that bug where a “double” of the player is created somewhere which also happens to be invisible the same way bugged mobs are. It could have been in snake pit where a connection issue happened causing this bug to occur at which point a snake eventually started attacking the double until for some reason it stopped, got killed or could no longer damage your double and maybe this had something to do with the infamy as well but I’m uncertain.
