I'm inexperienced in Warbarons, so apologize if this question/problem is stupid, but...
What is happening when I target an enemy army on the screen, but get an "error" message reading, "The target has changed! Verify if you really want to make this move" but when I click the OK button, nothing happens, so I'm unable to attack the enemies in question, whether out in the field or in a castle....
I'm playing a single player game against seven AI opponents...
