Not sure if this is a bug, but . . .
Game: 24495263. Turn 12
By playing Ironmongers, I had set up an action as my top card. So, I played Vassal. That card was discarded, which is correct. But, while the info in the game log did give "You may play [that discarded card] from your discard pile" as one of my options; I cannot find a way to actually pick this decision.
Unlike many situations in Dominion, there is not a hot link via the game log, so clicking there accomplishes nothing. Clicking on the action card on the top of my discard pile does nothing. On the main board, the only option I can see is the usual button telling me that I can play another action card from my profile (and this does work).
Am I missing something obvious? Or is this a true bug?
