When following fleeing units (I've only tested this as Unclean, but feel free to share your own feedback), my hero will stop every few seconds instead of running non-stop in order to catch his target. It seems that this hero (perhaps all heroes) will stop running every few seconds when auto-chasing a slower enemy, making it impossible to catch them.
