Collectible Card Game Headquarters

I've recently been trying to make a pauper quest world. In order to do this, I created a few new sets that just contained commons. I then created a world in the quest world.txt, made a block for them, added a draft ranking. So far everything has worked, except about half the time after I win a match, I get this error after I win the match, but before I choose which pack to choose from. I cannot tell if it is an error in my set or if forge is trying to award me a rare for winning but since the sets contain no rares or uncommons it is producing an error. I will attach one of the sets I created.

Any ideas to what this error could be from would be much appreciated.
