So I've been farming skeleton keys since I've reached light 400, since there isn't much else to do, and I've been storing them on each of my characters (5each) and then 5 in the vault. Once I accomplished that I've started to let them accumulate at the postmaster. So I had 3 stored in the postmaster and when I logged in today the skeleton keys on my main character (5) and the keys in the postmaster (3) are all gone. So I'm pissed because it takes a while doing strikes for even one key to drop and I just lost 8. Anyone else having this problem?
