Serialize scene asset GUID, and then visit the path & index of the scene

It'll give error & fixing button if the selected scene is not in build list or is disabled.

using SaintsField;

public SceneReference sceneRef;

private void Load()
{
    SceneManager.LoadScene(sceneRef);  // load by scene path (name)
    SceneManager.LoadScene(sceneRef.index);  // load by scene index
}
