Unknown errors causing loss, no challenge completion
While playing with Nissa vs. Chandra. My game froze, disconnected and had "unknown errors" a minimum of 5 times. I wasted 2-3 rounds reconnecting to the game but was still winning somehow. Finally, I got to the point where I could finish my opponent but game decided that I was defeated even though my opponent drew a piston-fist pummeler as his only card and I still had 4 health. I got my "trample creatures" challenge completed, but it did not count as a "completed game with Nissa" challenge. I also lost, which is completely ridiculous. Now this is something...
