LoadKN5() and skinned meshs

I was tring to loadKN5() into SceneReference with lua script. If the KN5 file had skinned mesh. (e.g. drivers, pit crews), game will crash as soon as I turn the view to the direction of the object. But static object likes cars were fine, I could load them into scene.
Is loadKN5() should not be used to load skinned meshes?
