[Mogel0815]

Hy,

after Starting a random dungeon we joined only with 4 Players and cant research because the message apears ,, Still 5 Players in Party!

After all leave the dungeon i got the message , you cant join dungeaon because 1 player not accept or leave the game., when i want to join a new Dungeon.
What can i do to leave the Group with the invisible Player?
