I'm unablke to upgrade RPK-12, both premium and (green, blue, prurple) ones.
The same for arrows (i'm not sure for uniques, as i never found them).
Is there restrictions for this items ?
Edit 05/10/2015 :
I have lvl 55 ingenier & fighter, lvl 16 weapon bench. The rpk12 and arrows don't appear in the weapon bench windows.
