So in testing, I am deleting everything out of the ~/.config/deluge/state directory and restarting the deluged service. The logging I have setup complains about some missing files, so it goes ahead and creates them.
Next, I add a hash.torrent file to the clean ~/.config/deluge/state folder, deluge checks it and begins seeding. The issue is, when I restart the deluge service now, that hash.torrent file disappears from the ~/.config/deluge/state location and subsequently disappears from the client.
