I was playing Gambit and One Eyed Mask dropped from the Primeval. It was the last match and my inventory was full, so I didn't have time to dismantle anything before being returned to Orbit. I went to my Postmaster to grab it but it wasn't there. Checked to see if it was unlocked in my Collection. Nope.
This is the first Y2 exotic to drop for me in the 200+ hours of Forsaken I've played, so I'm pretty heartbroken about it. :/
And before people start jumping on me for playing too much, I have a lot of time on my hands right now because I'm recovering from surgery. ._.
