Opponent played Noble Brigand, revealing one of my Tunnels. I also had a Trader in hand. By the text on NB, I should have been asked to reveal the Tunnel first, since that gets discarded before I am made to gain a Copper. However, I was asked to reveal Trader first, gained a Silver (which should have covered up my Tunnel and lost track of it), and then was asked to reveal my Tunnel.
