Game contained Castles (bane), Young Witch, and Bandit.
I had right-clicked on the Young Witch and the new interface was pulled up to show me the card and the stack of Castles in the bane. While I had this window open, my opponent played the Bandit, and my top two cards were a Silver and a Gold. I clicked out of the Young Witch display but the display did not come up to let me select the Silver or Gold. Refreshing repaired the issue and we were able to play on.
