I didn't get a bug, but I did see an interesting glitch that seemed to fix itself on the next turn. While playing against Eternal Phoenix, I used Aflatoxin on a Minor Phoenix. When it died, it didn't immediately replace with Ash, it simply went away. At the end of my next turn, a 0/0 blank creature with the phoenix ability appeared, which became Ash at the end of his next turn. I presume this was caused by some sort of code interference from the Aflatoxin. Figured I should mention it.
