As the title describes, I was playing a Chaos Dungeon with three other people and the first portal malfunctioned. If you click G or try to enter the Portal, you are greeted with the message ‘Your party is not valid anymore.’ The portal does not work, you can not progress, and the Chaos Dungeon can not be completed.
No solution that we could find. Had to exit the dungeon and take the Aura loss.
