First off, I realize Trials armor isn't generally available yet, but I smuggled enough Trials engrams in my postmaster to get full sets on every character. All of them work as expected with regards to transmog, EXCEPT the Hunter Vest (Photonic Vest) does not show up in the transmog UI to be unlocked. I'm positive I have the armor piece (I had two Photonic Vests drop, still have one on my character), but it just isn't showing up in the transmog unlock area of the appearance customization screen.
