Dupe bug in version 1.1.10

1. Open gauntlet gui
2. Shift+click to gauntlet in your hotbar, then gauntlet go into empty gem slot
3. Close gui, then you get back gauntlet again in your hotbar
4. re-open gui and shift+click the gauntlet in gem slot
5. then you get 2nd gauntlet

Confirmed, just tried and can recreate. You can do this over and over and get up to five gauntlets in the empty gem slots, just take them out, and rinse and repeat.
