I have a problem regarding the refining of the cosmos helmet. It is now level 4 refined and I want to upgrade it at level 5, I have all the materials including another unupgraded cosmos helmet to be "sacrificed" in order for the refine to happen. However, when I click refine, nothing happens and I get the following message "Insufficient Armor for Refine or the attributes are different (Upgraded" and it stops at "(Upgraded", I can't see what does it say next.
Can someone please tell me if I am doing something wrong or if this is a bug?
P.S: Here is an image with the errorhttps://imgur.com/52E5wrC
