Duplicated gem

Your bug report reference number is 2,460,976,154.

I managed to duplicate Fist of war II by cutting a support gem.

Steps to reproduce:
1. right-click uncut support gem level 3 in player inventory
2. select Fury of the mountain where Fist of war I is already socketed
3. cut Fist of war II

Observed:
Socketed Fist of war I is upgraded into Fist of war II
New Fist of war II is created in player inventory.
