Matt, there were none that came with the game. But there are a few Fans who like to design extra stuff for the game and sometimes they share their methods on board game geek.

Someone had designed the instructions for making a set of boxes to keep the different decks of cards in for the base game. But when the expansion was released, the old boxes weren't nessessarily all the correct size to hold everything together properly.

The first poster was asking if anybody knew if there were updated instructions. That's all.
