At the request of The_Cortez:

My only gripe (that I haven't seen posted before) is that assassins do not track some victims. If I send an assasin after a spy, and the spy moves, my turn ends, then the assasin has movement points left and moves, he still go through the "assasinate" motions, even though the spy has moved to the next square! The assasin should either track the spy or let me know he has lost the trail.
