Has u can see in the images, i still in DF group instance, like if a phantom player being in there.
Can't leave group even with ''/group leave'' cause ''You are not in a group'', and can't invite no one cause they're not in my instance (Pit of Saron RDF).
Now the important thing... ¿How can i fix it?

copy paste this on chat:
/script LeaveParty()

Actually, that works... Thank u! n.n
