I played this game back when it came out and ran the Leviathan Raid back when it came out and got the shader (as you can see by it being on guns it couldn't role on) and then stopped playing until beyond light came out and was told I could get the shader from collections but it says I haven't unlocked it and was hoping when the shader change happened this season I would unlock it again but still don't have access to it. Anyone know why this is or how I could unlock it?
In order for an item to be in collections, you would have had to have had it in your inventory after Warmind was released, as before that, nothing was tracked. Being on your gear does not count. If you do not see it in your collections at this time, all you can do is wait and hope Bungie brings it back at a later time.
