So I was doing VoG and I had made sure if anything went to my postmaster it would be a primary. So we beat Atheon and the only slot full is primary weapon. I got the ship and some ascendant shards. I had something from the postmaster and I had thought if gotten a Vex. Turns out those ascendant shards filled up that section of my inventory and I got 3 ascendant energy. I was so pissed.
