This is something I did on my own, and later found you had suggested to another user in the forums:
Debug.LogError("Unable to execute function with ID of '" + funcID + "'. Make sure there is a script alongside TNObject ID " + objID + " that can receive this call.\nGameObject: " + GetHierarchy(obj.gameObject), obj.gameObject);
This will make tracing RFC ID mistakes easier to track down when you have complex objects or similar objects.
