I'm new to the game, but a quick search didn't seem to turn up anything on this specific issue, so I might be missing something, or it's a new bug...
I'm on the third scenario of the first campaign - where you hunt the dragon Black Fang.
I'm at the Temple location with my druid, and I used Augury at the start of my turn (before exploring). It let me discard it, but then nothing happened. I didn't get the UI to choose a card type, nor did I get an option to recharge instead of discarding it.
It's worked before, in the second scenario.
