bug fix

Noticed a bug with the Yu-Gi-Oh collection accounting system. I did not want to keep track of my card collection anymore and focus on video games, so I went and clicked REMOVE with all of my card entries. The issue is, while it currently says I have no Yu-Gi-Oh cards in my collection, it also did NOT remove the multiples of cards I had, so I simultaneously have 0 cards, and 7 cards worth $16 in my collection. 

Seems to be a bug.
