At 16:00 (GMT) on 21/12 I crafted a 4* R10 Maw Of The Deep Legendary Gem. I did this buy using my existing 5* R10 Spiteful Blood to do a gem power transfer to make the gem torment and gain the gem power - I then used the power and my 73 maw gems to make a 4* rank 10.
After ranking the maw to rank 10 I wanted to test swapping the gem power back so that I could still use blood for pvp. When I used the gem transfer mechanic the blood became rank 10 but my maw of madness and the 73 duplicates disappeared totally, and left me with 2300 gem power.
On other gems the power transfer mechanic simply swap the dormant back and forth, however in this instance is remove the dormant on 1 gem and salved 73 maw of the deep gems for 2300 GP.
Please can you contact me to resolve this.
