Hey forums

Today I was checking my Retainer's inventory and saw I had 2 Sands of Time in her inventory. I found out I can use them to upgrade Whethered gear from ilvl 100 to 110 so I wanted to withdraw them, but after I did it, the 2 i had suddenly turned into only 1 being in my inventory I triple checked EVERYTHING and EVERYWHERE in my Inventory, Armory Chest, Retainer's Inventory, completely gone!
Is there anyway to get it back?
