If it's not too late to suggest: I have made multiple mistakes during play because I thought the region I selected was for my caballeros. But to my horror, it was for the action card. There was no way to undo the mistake. The turn was ruined. Can this be idiot-proof better? Possible fixes:
1 - the player must select which they want to do: placing caballeros or taking the action. Right now, by default, it takes the action.
2 - allow players to reset their whole turn
