I just realized you cannot rollback when activating a card with the expension. I think it should definitly be an option before to actually take the action, because you can easily click on a card by accident or just activate the wrong one when you have two similar ones.

I agree completely!

The top bug report/feature request for this game is:
#132785: "Quick confirm button at end of turn“

Please vote for it and add a comment about needing undo for the expansion--that's what I just did.

It has been the top bug report for ages. Another poster assumed development of the game was abandoned because there has never been a dev response. With the new expansion released, that clearly isn't the case, so hopefully they will add this capability!
