Slow Medic + Fast Bodyguard = never ending chase

[Tolwrath]

So in preparation of a journey, I set all my members to bodyguard my slowest character. I realized one of them was wounded though, so i set my slow character to medic to heal them. To my amusement, the bodyguards do not acknowledge an attempt to heal them, and instead just run ahead to stay in formation. So my healer how was trying to run to the bodyguard to heal them could never catch them, resulting in an endless chase.
