It's a simple topic, but to post something that many do not realize, a DC recently occurred in Aika, so far normal, only that many items are gone, others became, sets and items that turned gold, lost items, mostly double.
So if any item your short or appear lost another after another, do not be surprised, you're not the only one, unfortunately Ongame has not commented about whether something will be done quickly for the return of items and gold.
