I woke up this morning and checked my mail. I had 5 letters from the Postmaster in my mailbox, with the following items attached: Netherwind Robes, Robes of Transcendence, Pure Elementium Band, Netherwind Crown, and Crul'shorukh, Edge of Chaos.
I don't remember rolling on or winning the items; I just clicked greed on every loot box that came up, because I didn't really care about getting loot or what I got.
Why were these items in my mailbox? Did I win them after I logged off, and because I was logged off, they were automatically sent to my mail? What should I do with the items?
