Idle Online Universe RPG

I am sorry if this is posted somewhere i didnt see it. starting today when i refresh or do a chall. always come back to party is full.... and then i go rejoin it in find a party list.
and Duo or group still does not work for me

just happened again. bsmtest got a duo up so i jumped on it. and came back to the party issue. I am not sure how he got the duo to work? does that only work once you hit 40 plus?
