Player both "zZz" in a group and online in another group

[magical1ne]

while in a party if you join a challenge then disconnect from the game while doing the challenge it drops you from the party you are in. after refreshing and trying to rejoin the same people  grouped with it will state Sorry, this Party is full.

Edit: just confirmed from other party member i appear offline (zZz) in the previous party while i am currently in a new party
