I understand the trainer isn't really supported, but theoretically, if I can get NaN in there, the same bug might be in 1.19. I was playing a Fire Lance deck, and Paradox (hehehe) had a Mirror Shield up. I wished to end on my own terms, so I played a Lance against his health. Mine dropped to 0, I lost, and then I went to the losing screen w/ no rolls on the slot machine. It said I had NaN electrum, and when I went to the menu, it said it too. Do you need a shot of the menu?
EDIT: This might be a glitch to unlimited funds; More Money didn't do anything, at least visually, and I seemed to be able to buy any card I wanted. I bought 100 Nymphs no problem.
