My library has just gone bezerk. I now get multiple stacks of the same card, stacks of "blank" cards, and half my cards are missing, and I now have several cards I never had in the past - for example, I never had a Discord, now I have 3 stacks of them - 1, 5, and 6. I also have 12 Marks of Entropy and 18 Marks of Death in my library. But my Arctic Squid and most of my other Water cards have vanished, as have all my Death cards other than Arsenic (which I never had before), and some Bone Walls. This happened on the Beta (0.43) site, and I went here - saw the comment that 1.0 is up, and my deck is the same over there.
