Sometimes my Sov will appear at one location, but the tile he is in, is a few tiles away. I even need to find that tile in order to select him.
Ive also had it where combat between an enemy Sov and wolves in my city(left them in a city as guards, from the wolf quest) moved 1/2 a screen away to do the combat animations.
Forgot to take screens(and how...), will do if I can.
