My complaint:
So I have played the viking quest and I i have a complete empty set, Darwin without a single gold card in it, I have played the Viking quest and my supposed first gold card I was given already gotten gold card, now on the 15th of December the Viking quest gave me a previous gold card again instead of the new gold card .
Suggested solution:
Please start giving me my gold cards from the Darwin set

Same exact thing just happened to me! Did they ever compensate you for it?
