I have both the MY_Controller and MY_Model in the application/libraries folder (so that all controllers and models regardless of in a module or not can access them). So, CI should be picking these up, but it's only picking up the Controller extension.
The controller and model accessing these extensions are in a module.
The controller extending MY_Controller works as expected. The Model extending MY_Model throws a 'not found' error on the model trying to extend it (it finds the model, but not the MY_Model it is extending).
When I change the model extender to MX_Model (file name, class name, and extends declaration), it works as expected.
