Items disappeared from Chest?

I was moving some items around in my Xunlai Chest, when two of them just disappeared as I switched their places. One of them was the Bison Cup, not sure what the other was. Is this a bug? Anyway to get them back?

What? Man that is Craze. I would go APE!

did you check to see that you maybe didnt move then into another tab or accidentally double clicked on one and equipped it like say with a staff that won't show an offhand in your weapon set box (if your inventory is closed)
Why, the bison cup is kinda crap...

Oh, haha. Yeah that was it. I accidentally equipped it somehow. Thanks.

/palm meet face

silly you

but this did actually happen to me once, sorta. I d/c as i was dragging around an item, when i came back on item was gone. Wasnt to fussed, think it was a rune or some mats.

If you have the merchant window open at the time, you can accidently sell things by d/c'ing

It's happened to me before too. Honest mistake, but one that freaks you out if you haven't noticed.
