I was in a RDF in the early hours of this morning, a Shaman left the group.
The instance remained full, we couldn't recruit a 5th member.
I am now stuck in an "Instance Group" I am not in a party, cannot be invited to a party, however I have the "Instance Group Leader" green flag on my character portrait.
I'm stuck in a party with no members, can't talk in party chat, can't join a group or be invited, cannot queue for another dungeon on the RDF either. Says a member of the group has dc'd and cannot queue.
Has anybody else had this issue?? I cannot leave group inside or outside of the dungeon... Nothing.
I am facing the same issue on one of my characters. I did this as skullatbash mentions, then a full restart of the game but I am still facing the issue.
