So I’ve noticed that my nickname disappeared from the Unreal Engine Credits even though I’m the engine contributor. There’s this message:
It makes sense, but I don’t know which information I should fill in my Epic account, I think I have everything setup correctly. It’s a very unclear instruction.
I’ve already contacted the Support at the given page, but they delegated me to the https://www.unrealengine.com/support which basically leads to the forum 
(or UDN, which I don’t have access to).
So… what do I have to do to get my nickname back in Credits actually?
