Maybe it's just my memory acting up but I am absolutely certain that back when this game was in Open Beta, there were items I had that I no longer have. I remember having an Aegis. I also remember having the Dragon Scale shield. This is the extent of my memory though. Could a moderator perhaps check through the logs and see every shield I've ever owned? Is such a thing possible? Every time I return to Spiral Knights, I cannot shake the notion that I had more than what I currently see. At the very least, the results of such a check would reassure me that all is well.
They reset all characters when they did the official release. So you wouldn't keep anything you had during the beta (except purchased CE)
