I logged into Destiny 2 for the first time this week today (friday), only to realize my Postmasters inventory was empty on my Warlock. I filled up the postmaster + inventory on all my character when we had double nightfall drops on Lake of Shadows. Now, without playing this week, I've somehow lost 10 shards and 50 prisms. I've still got everything on my Hunter and Titan, but I'm not too happy about losing a small fortune in upgrade currencies for no appearant reason at all. And yes, I'm 100 % sure I've not accidentally dismantled them. Neither have I pulled them into my inventory via Destiny Item Manager, because my inventory already holds 10 shards and 50 prisms. And they can't be stored in my vault, so where the hell did they go?
