I have the same issue for the past 4 months.
Every time i try to craft golden Mana Burn or golden Consume Magic, i get the error “Collection error! An error occured while processing your request. Please try again later” . I tried it through my PC and my phone but no luck so far.
I even tried multiple times making a ticket to fix the issue but AGAIN i get the error “You can’t submit this ticket. An error has occurred. This may be a temporary error, so please try again later.”
So what do i do now?
