Can't save map, graph is linked to external private object(s)

I’m not 100% sure, but that bug. When i’m adding component to my actor with NewObject<>() I’m lose the ability to save the map too.

Try this:

  1. Remove this object from scene.
  2. Comment line 53 and some another (that there was no compile errors).
  3. Compile.
  4. Place object to the scene and save. In my case editor show no errors.
  5. Uncomment lins.
  6. Compile again.
  7. Change somethings on scene and save.

So, in my case this solution helps. But, if you place this object to the scene again this “saving bug” returns.
Sorry for my english and have a nice day!
