I have always wanted to use the deep stone crypt warlock chestpiece as an ornament, however, for some reason it's just not there, same goes for my gauntlets, but my raid boots, bond and helmet are still there, I am not sure if it's only them I am missing, but for now they're just not appearing (I also don't have too too much armor since I started with season of the hunt with my warlock so it's not like it's lost somewhere there.)
