Awiergan Scrolls broken?

I’ve played DA2 about 4 times now, completed the story line and all that important stuff, but I wanted to complete it by finding and completing all the quests I could. 

One quest, which seems to be notorious for having an issue, The Awiergan Scrolls: Pride Unbound is still giving me issues despite how many articles I’ve read to try and fix it.
I’ve done a rerun and attempted to find each and every scroll going through each quest again and nothing worked. I set another quest as my goal before setting Pride Unbound as my current, the hidden lair still does not pop up.

Is there anything I should do? I play on the Xbox One and haven’t had issues with the game at all. If anyone could help, that would be amazing.
