Corrupted LynBlade chest bug

[CiniusShade]

I got "Sealed consumed lynblade" out of the "corrupted weapon chest". When I unsealed the "sealed consumed lynblade" and it didn't change to the correct item I need to upgrade my weapon. I burned 2 keys on this bug bought from the Hongmoon store. Not only that but people are taking advantage of this bug on the Market by making this weapon 3-4x's the price of all of the other class weapon upgrades. 

 

I would at the very least like to be reimbursed for the price of the 2 keys and I will try my random luck on opening chests with no keys.

 

Thanks
