I currently own and can equip the new Trials of Osiris Hunter Chestpiece, Pyrrhic Ascent Vest. However, it does not appear in my Appearance Customization selection for unlocking the universal ornament. It doesn't even show as locked. It just doesn't show at all, even while equipping the piece. I currently have 6 Synthweave Strap as well. I was able to create universal ornaments for the other 4 pieces of armor for the new Trials of Osiris Pyrrhic Ascent Hunter set. Sorting does not fix the issue.
