		-- * character deparenting is a Remove instead of a Destroy, so signals are not cleaned up automatically.
		-- ** must use a waitForFirst on everything and listen for hierarchy changes.
		-- * the character might not be in the dm by the time CharacterAdded fires
		-- ** constantly check consistency with player.Character and abort if CharacterAdded is fired again
		-- * Humanoid may not exist immediately, and by the time it's inserted the character might be deparented.
		-- * RootPart probably won't exist immediately.
		-- ** by the time RootPart is inserted and Humanoid.RootPart is set, the character or the humanoid might be deparented.
