It seems to be stuck around the time Thraal shouts “IS THAT ALL DEMON?”
Thrall is walking around in circles, despawning and shouting his lines out of order.
When we are supposed to enter the throne room the walls fall then Thrall and Slyvan run through while everyone is stuck behind an invisible wall.
Adding on this from the character I am using for the event,
The ending of the event RP also triggers while the rest of the RP event is still in motion.
I was able to get it to work after around 10 hours. The trick is as follows:
Don’t worry about Lady Sylvanas or Thrall. Sylvanas might just randomly despawn after getting to the elevator. Maybe she respawns at the center in the bottom floor, but she probably wont. Thrall will 95% slowly walk to the Throne Room and run his laps, don’t worry about him.
The most important thing is to kill all the bosses yourself! They are they key for the event triggers! You will see the confirmation at the top that the horde conquered the parts of the city.
Do the following (slightly inaccurate because it’s from my memory):
In case you got stuck, you can leave Undercity through the Sewers in the West. Just walk out and wait until the event resets.
I hope this was helpful and Blizzard finally fixes this…
It’s still bugged… What did you hotfix
There is nothing to start the event. Been standing here for 40 minutes and thrall is nowhere to be seen.
Thrall works up until varimatras collapses a tunnel then thrall stops attacking enemy npcs and runs through the rocks in to the throne room and he just runs around the room in a circle doing nothing at all.
Sylvanas and her buff vanished at somepoint once we entered the undercity after the jump down.
Abandoning the quest does not get your uc and ogrimmar unphased from the quest phase and honestly, that’s the worst bit.
Thanks for the additional info everyone!
We’ve identified some additional aspects to this issue and continue to work on a final solution.
More updates in this thread when we have them, or keep an eye for changes to the relevant support article here:
Bugged for me and all my friends too. Happened around 5h ago today so after the morning hotfix.
tl:dr Thrall’s dialogue and the event seemed to reset after the end boss, Thrall disappeared, rubble came back and everyone was stuck untill HSing away.
Then the longer version:
Brewfest music and goblin laughter everywhere (not the best raid music, could brewfest mess this up somehow?).
Thrall kept disappearing/reappearing in different places after we got to the elevators.
Sylvanas was never seen after the event started.
We continued killing the bosses and sometimes Thrall appeared for a bit.
In the end we managed to kill the end boss, but after that when Alliance was supposed to arrive, Thrall started his dialogue from the beginning of the event (“join me behind the walls of Undercity…” or something like that), he disappeared, the rubble in the hallway appeared again and everyone was stuck in the end boss room.
At that point we were waiting for quite some time until we had to give up and HS away.
so what happends to all the brewfest tokens we lose from not being able to do the dailys because they are phased? I was doing them everyday to save up for the outfit for the achievement in dalaran and now i won’t be able to afford it
I’m kinda angry and usually don’t write in the forums, but this situation has to change!
You can’t just have peoples time wasted and say you can not provide a workaround or solution to fix this.
Either deactivate the quest, tell people it is bugged the moment they accept the quest or just straight up let us complete the quest without the event.
We were a group of five and didn’t know about the bug. Do I really need to wowhead every quest I start?! Is there gonna be compesation for all the time wasted?!
Stop making people mad! PLZ!
Thank you!
ps: I forgot to mention the Quest is still bugged! Server EU Razorfen - 29.09.22
Hey all,
As an FYI, our developers announced that they’re working on a workaround to skip the scenario, while they work on a permanent solution. You can find more information here, if needed. 
Every one of these solutions would require a developer to work on this for several minutes / hours, which is usually time that would be better spent on fixing the actual issue. There’s unfortunately no magic button that would allow programmers / developers to implement a solution or workaround.
While it’s obviously not a requirement, the same thing would apply IRL when you have an issue with something, and Google it to find if this issue happened to someone else, or find a possible solution.
That being said, thank you for your patience.
Im in a weird situation… I picked quest and phased out. Then tried to do it but couldn’t. So I dropped the quest entirely hopping it will fix phase out issue. But no… I’m still phased out in empty orgrimmar. On top of that I can NO LONGER take quest again or talk to Thrall.
I don’t really care about this quest anymore. I just want to use Orgrimmar city to buy honor mount. I can’t buy it anywhere else.
Blue post was saying about 24h solution to skip it. I really hope it will come in next few hours…
Also bugged for me thiis quest thrall diddnt appear at the start after i talked to Voljin only Sylvannas . died 5 times in the courtyard after almost soloeing it with 40k health . threw away the quest relogged and now nothing no portals to undercity nothing ?
Quest is also bugged for me. It just restarts permanently on different phases. For example, we started fight with the end boss then Thrall shout again from the entrance.
The most frustrating probrem for me is that there is Brewfest in Orgrimmar. And with the city phased out I cannot participate in it. Farming prize tickets is crucial if you want to do all the achievments and get a pet. I don’t want to wait for another year.
still bugged xD
Holy moly I just finished it! It still is bugged, but somehow stars aligned.
As you can see at the top of the screen, you’ve not finished all the encounters. While you’ve finished the inner sanctum, you’re missing the graveyard at the top (the huge mob waiting after the gates). Once you’ve done that event, the triggers for the royal quarter will start.
So I’ve hearthed, abandoned the quest and am now stuck forever in the wrong phase. I can’t travel to irisfall glades because portals hop me in UC and the zepps dont work in orgrimmar, which is phased as well… How am I supposed to talk to the reset phase NPC when I cannot get to him? You should have put a reset guy where the portal exists in UC as well.
Exit through the sewers.
So I’ve also aborted the quest and ported out. Now I can’t get back to the start because I can’t restart the quest with Thrall. What now?
No need for some nuclear physics tactics. I play Horde on Gehennas and did q without problems doing this…
The first time I started q waited probably 1h on Thrall and he did not show up. So I talked with npc Zidormi, she is located near the first Undead banner under a huge light ray You can’t miss her 
Talk with her to put u on current time before Battle for Undercity! That is how u will be able to take Zeppelin, using Ah all the stuff that you were not able to do during the quest even Orgimmar is okay.
Then take Zeppelin to Orgimmar and again Zeppelin to Undercity!
Then again speak with Zidormi to put u back in Battle for Undercity time and Thrall will be there.
I assume the portal that Thrall gives u makes a bug and you can’t continue forward with the quest because he phrases u in some weird timeline.
You can maybe skip my step by skipping Thrall portal and straight taking Zeppelin and when you’re there talk with Zidormi to phrase u in time BFU. And dont run from Thrall and Sylvannas where they going u follow them. gl!
