Forum Quest Bug " The Battle for the undercity"

[MaikeGauer]

So I started "The Battle For The Undercity" in which I'm supposed to talk with Thrall outside of Undercity, but when I do nothing happens and I can't advance any further. I also can't go back to the normal Orgrimmar nor Undercity because it stays the same as if I were doing the mission still (like in a different type of layer in which there are no players or npcs). I already opened an ingame ticket (btw no response yet).

I would like to ask you to remove me from the quest lob. Thanks

Open a ticket in-game and ask GMs to phase you out of the quest.

I already opened a ticket, it's been 2 days and still nothing...
