After the recent hak update, a player in discord said they can't enter the world as a ghost, because they can't relevel as a ghost.
So either let ghosts be able to level up in the OOC area, or let them enter the world without leveling
e: to clarify, I think ghosts should be able to enter the world, for spirit RP reasons. Bad enough they died, are out possibly weapons & gold, and are possibly corpsehidden. Not being able to spirit RP for OOC reasons out of their control would certainly feel like salt in the wound to me.
