title: Some objects were not cleaned up when closing the scene
body: <p>This error appears in console on scene load:    </p>
  
  <blockquote>
    <p>Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)</p>
  </blockquote>
  
  <p>I know it's because I <code>Instantiate</code> an object in an <code>OnDestroy</code> method  and I know <a href="http://answers.unity3d.com/questions/169656/instantiate-ondestroy.html" rel="nofollow" title="test">how to fix</a> this problem on application quit. But I don't know how to fix this on scene change with <code>SceneManager.LoadScene()</code></p>
  
  <p>Is there any method for this need, something like <code>OnSceneUnload</code>?</p>
