The Vvardenfall quest "The Heart of a Telvanni" is broken

Hollyniss

Can't progress the quest because of a bug so I abandoned it. I was at the 'escape the mine' stage. Couldn't go through the damned door as it was greyed out. So I went out through the front. That didn't work as it didn't register that I went in, in the first place. Relogged, exited and entered several times through the front hoping it'd right itself. Nope. Saw an old post where people had this bug back in 2017, it's 2021 now...maybe you'll fix it sometime this decade...at this point though not going to hold my breath. That's two broken quests now this week, let's see if I can get a third...

Here you go my dude: https://forums.elderscrollsonline.com/en/discussion/367178/bug-on-the-heart-of-a-telvanni-quest/p1

But yeah, I'll post the legit fix:

1. Abandon quest
2. Start the quest again and get up to the point where you pick between the two options.
3. Pick opposite option that you picked first
4. LOG OUT completely for at least 15 minutes. 30 to be safe. This resets the instance's AI, which is the entire reason why the quest is hanging; the AI is bugging out and not sending two dudes to the interactable door you need to go through which need to begin dialogue for the door to allow you to open it.
5. Enter the mines after your 'break' and it will either instantly progress it to the door being opened, or you'll have to drug or kill the guards.

I encountered it on two characters. First time hitting step 5 it had no-one in the mines but the two talking at the stuck door, instantly progressing me through. Second time hitting step 5 I instantly had the option to drug a guard and the quest zoomed to the 'go through the door' state with the two coming to talk at the door instantly.

Actually it's much simpler than that. The bug occurs when you don't let them finish their dialogs and you rush the door. So you'll have to abort the quest, but next time just pause before each door and let the dialog complete before proceeding.
