Mouse over system not destroying mouse over after object death, fix?

ok so im working on a 2d space game where players can hover over other objects and see details about them and i cant for the life of me figure out a little bug that has appeared, here's the code for Reference:
`

 public class MouseHover : MonoBehaviour
 {
     public GameObject MouseCircle;
     GameObject Tracked;
     bool Good = false;
     void OnMouseOver()
     {
         if (Tracked == null)
         {
             Tracked = (GameObject)Instantiate(MouseCircle, gameObject.transform.position, Quaternion.identity);
         }
         else
         {
             Tracked.transform.position = gameObject.transform.position;
         }
         Good = true;
     }
     void LateUpdate()
     {
         if (Tracked.transform.position != gameObject.transform.position || Good == false )
         {
             Destroy(Tracked);
         }
         Good = false;
     }
 }

the problem is, is that if the object gets destroyed the mouse over is never destroyed leaving a rather ugly circle just sitting there.

any help would be much appreciated
