I’m having issues with this too. I’ve searched the forums to see what I missing, and can’t find it. I’ve run this dungeon three or four times now, and the first time I did, I went back to my hall to store it, and now there is the gold translucent outline. But the other artifacts are solid and in place. I also do not have credit for it in the achievements, though I am getting the pillars of creation quest line. Not sure what’s missing here.
