Ya it seems like bungie thinks this is a community conspiracy because they haven't been able to replicate the problem at bungie. I along with many others have also had my skeleton keys disappear from my character inventory when you have the max of 5 it glitches out if you have 1 waiting at the postmaster, did you have any fragments at the postmaster by chance? This is a major issue that things are disappearing from people's inventories and would think bungie would take these reports seriously. I don't play much anymore until they fix this problem I refuse to put time into such a bugged out game.
