Weird party bug ( Got stuck .. )

I got stuck to a party with a player.
Whenever i go to my HO i see him in my party. But actually there is not a party.
And in that situation , i cannot invite people or cannot get invites.
I logged off and logged in - closed the game and restarted but it is still there.
I go my HO and it shows me in a party with that person. When i try to leave pt or invite others it says '' this party does not exist ' ..

Edit : When i go epilogue town or into another map . Party disbands. He leaves. But when i go back to HO it is still there...Omg thats really bad and i cannot invite people there :c

try selecting another HO see what happens then.
