I have created a Demon Hunter and finished the Mardum questline. After that it brought me to stormwind where I had to finish the Demons Among Them quest. I finished it without any issue but after turning it in I am stuck in that phase of Stormwind. Meaning the mobs are still in the throne room and it is though I haven't finished the quest. I would usually ignore it but now I have the Tides of War quest which requires me to go into the throne room and I can't finish it. This happened yesterday and I'm still facing the issue and can't even continue the game.
I have tried the following:
Unstucking through the game
Unstucking through the website
Hearthing out
Doing other quests
Logging out
Exiting the game
Using the /reload macro
