Game crashes if you remove a card tied to Mysterious Pyramids

[SineSwiper]

I ran into an opportunity to remove a few cards, though a quest, that I no longer wanted that were tied to relics. One of them was tied to Mysterious Pyramids. I'm not sure if I played a battle after that, but as soon as I continued my game from a save, and tried to enter a battle, it will consistently crash with:
