I'm playing with a mod race with nice assassins and I have come to hate a stupid little flaw in the game:
You get no message of any kind if you order an assassination and there's no target. I've got 20+ assassins out there handling much of my initial expansion and it's a royal pain keeping track of whether a province is cleared or not.
What I want:
was unable to find a target to assassinate. The goto button would take you to the assassin.
