Can someone tell me why I get Draw instead of winning? (I had 20 Life)

This looks like a rare bug we've seen (and are trying to track down) where it basically just shows you the wrong screen. In the cases we've seen, it's still counted and processed as a win on the back end (event courses update properly, daily/weekly wins awarded, etc.), but the wrong screen is shown on the client.

We apologize for the bug, and we're trying to hunt it down
