WotLK stuck in a dungeon group by myself

[RKSmith45]

stuck in a dungeon group by myself, cant leave it (game shows im with 3 "Unknown"'s in the group), and i can't join a different group. Playing on Lordaeron

3 unknowns? Means their names are yet to be loaded. May take a while sometimes.

If in an invisible party (not in party, but game thinks you are in one):
/script LeaveParty()
