I have the same problem, the content is locked on Steam and Android, but DLC is visible as owned on Steam account. This problem appears when I log into Asmodee account.
I have the same problem. It is sometimes possible to cancel whole action and retry to do it. Then you're able to move a card from discard pile. Unfortunately sometimes you cannot cancel (especially if it's a card played by other character). We also need a button that retrieves a highlited card from the discard pile.
