Nightmare Dungeon Bug

Need to be in a party so this is a very simple bug be in a party start a nightmare dungeon you and your friend go inside the dungeon promote him to party leader then he needs to hit decline on transfer to new world state or whatever it says then complete the whole dungeon level up your glyph and before you guys leave the beginning person who originally leader who started the dungeon leaves the party it will kick you out the other person will now press E and leave dungeon. At this point re-request to join his party and have him make you party leader it will ask you to make the world goto your state hit decline walk back in dungeon everything has respawned promote him back to party leader rinse and repeat one dungeon 80000000000000000 times.
