I mean like really, is all this jumping through hoops necessary at all? I've been saving props to library for 25+ years never had a single problem.... Add prop to library_click on preview image to reload... It always works....Am i doing it wrong or are the propeller heads Rube Goldberging  something simple?...LOL

The reason someone might want to externalize the geometry is because if it's large mesh and has a large file size, having multiple instances of it in your scene might bog down the scene.  Externalizing the geometry will save you some resources.
