Necrolord Assault Bug - Blowing the Horn segment

Here to report perhaps a different bug than all the others I’ve seen. My DK is on “Use Draka’s Battlehorn…” part of the assault. I get to the gate, use the horn, it spawns the NPC’s gatecrashers, etc, but they don’t do anything. The gate remains closed and i can’t finish the assault. I’ve done multiple things to try and fix this - left the Maw, logged out, came back, switched toons, used a glider to get around the gate and use the battlehorn (still doesn’t work). Nothing I’ve done has helped and I can’t find anyone else who has run into this problem. Please advice.

Thanks

Having this exact same problem, have yet to find a workaround.

i had the same issue today, so is there noa solution but i could finish it using my binding key for a extra button even if you cant see the horn’s button
