I know for sure that I've completed the Malvigr quest, but it still remains stuck open (as if I didn't complete it) and not being able to complete it.
In the "completed quests" list, it does not appear, nor on the map. I've completed "The Relic" arc thinking that it's a pre-defined order, but it doesn't relate.
I've attached 3 screenshot representing:
- current quests;
- last X completed quests;
- the world map tracking "Malvigr" quest.
In case attachments aren't shown, here's a link to those 3 screenshots: https://imgur.com/a/4V5jTUV
