I had 4 mages in my army and I moved them into the back corner in the tactical combat. When I did this the enemy army, which consisted of 3 juggernauts, stopped moving when it was their turns. I'm guessing that this is because they were targeting the unit in the back corner which they could no longer reach?
Here is how it was basically laid out: The Ms are my mages and the Js are the enemy juggernauts. The bold M must have been the target for the enemy, since it was my wounded mage.

The juggernauts moved for their first turn, before I moved my mages, but did not move again after that once my mages were in the above formation.
