At the moment, the new DSU built after the update from 1.0.1 do loose its content after a while. This problem was reported by a few people and after looking into it, i see indeed dissappearing items. The whole DSU is getting from one to another moment empty. If you have further informations on this, go ahead. This is also an information to all new players, to maybe not use them, until this is getting fixed. Because if you do loose items with this bug, there will be no refund.
