Kingdom has Horse Trader, and the attack card Margrave.
Turn 10. Lord Rat plays Margrave, while I have Horse Trader in hand. But, I'm given no opportunity to use its defensive ability. I used Undo to try all 3 possibilities. (ie, 1. Tried discarding 3 cards, which included the HT. Nope. 2. Tried discarding 3 other cards. Nope. 3. Looked all over the screen for some hidden button to click on, to activate the HT defense. Nope).
Is this a known bug? Is it an actual bug, or am I doing something wrong, somehow?
