I did a few runs of the Equilibrium dungeon during Guardian Games, and didn't grab the loot from a couple of the chests. After the dungeon, I mistakenly turned in a couple diamond Guardian Games medallions which immediately filled my postmaster and deleted all the dungeon loot I hadn't yet claimed. While I understand that if the taken crystal was there it is now permanently lost and un-earnable, is there a way to check to see if this was the case so that I know to stop grinding for something that won't drop?
