Exception when registering the second clone of a template when a CollisionShape has been added

I have a template I made in which I have a few simple components (scene, T3DBox, rigid), but as soon as I add a collision sphere to my rigid component I get the exception below when creating the second instance of the template. The first instance just doesn't show up. It seems to be having trouble registering the T3DBox in the scene group, _sceneClientList is null.

System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
