Monster(ous) Book pineapple up.

Just checked the damages. Same issues with using sets. Cards went from 121 -> 34. I noticed that the cards kept seemed to be the ones I had more than 3 of, but I'll have to double check. But there does seem to be a relation since the only cards I have now are the nub island ones, two bosses, and some guardians in ToT.

EDIT: Personal update, getting new cards leads to the same problem. Obtaining a new set automatically put it into the one selected, but I still cannot change sets. Working on completing a second "New" set now to see if I can at least select between the two.
