If you go flawless this weekend to the Lighthouse DO NOT dismantle any gear you have with the Cobalt Clash shader attached to it; the shader will not be added to your collections and it'll just disappear along with the loot you dismantled. This is a pretty annoying bug that's shown up and that lot of people (myself included) are having an issue with right now. Very frustrating to go through the effort of going flawless and not be able to have the shader as proof of your efforts. I'm hoping Bungie will be able to address this issue and reimburse players who went flawless on Trials with the shader. UPDATE: Turns out Bungie made a booboo with the wording on the shader and having it show up in collections; apparently you're never supposed to be able to unlock it. -__-
