How to return an enemy to its original location after losing aggro?

So basically I have an enemy that, once you get close enough, will chase you around and try to attack you. Once you get far enough away, it will run back to where it was originally.

The issue I'm having is that once it runs back to where its starting point is, it just falls over and keeps running and falling over around that area.

Here's what I have for code for that section:

 if (inAggroRange()) {
         //In aggro range
             if (!inAttackRange()) {
                 chase();
             } else {
                 animation.CrossFade(animationAttack.name);
                 attack();

                 if (animation[animationAttack.name].time > 0.9 * animation[animationAttack.name].length) {
                     impacted = false;
                 }
             }
         } else if (!inAggroRange()){
             //Go back to home position
             if (!(transform.position == enemyHomePosition)) {
                 animation.CrossFade(animationRun.name);
                 transform.LookAt(enemyHomePosition);
                 controller.SimpleMove(transform.forward * speed);
             } else {
             //Enemy is at home position
                 animation.CrossFade(animationIdle.name);
             }
         }
