Any news on this one? This issue is open for almost a year now with no fix in sight. This is the most annoying thing that happens to me while playing.
I play on PC with season pass. And by the looks of it, the the runes i buy from the vendors disappear from my gear after a while.

Yes, same quest, same happened.

World Event: The Demon Odor of the Tithe is still bugged with patch 1.1.0
The NPC is not spawning.
The jars are spawning under one of the movable objects, making it impossible to move. This is the only Mystery I'm missing from 100% completion, so pretty sad it remained this way.

World Event – The Horn Of Ragnar

Completely stuck with this one. Decided to side with home owner. But can't attack Bron

Bug found: Lunden - Anyone, I'm stuck mystery
Description: The Norse Man is not inside the warehouse, so the event to free him never starts.
Patch: 1.0.4
Platform: PC
