Codeingiter & HMVC Cannot find controller if level 2 subfolder

Question

If I put the controller in a subfolder of level 2, the "categories" will not find it

application > modules > catalog > controllers > forum

application > modules > catalog > controllers > forum > categories

// unable to locate
application > modules > catalog > controllers > forum > categories > Category.php

// able to locate
application > modules > catalog > controllers > forum > Category.php 

The question can be changed MY_Router.php so that you can correctly identify the folder and not use it.

I am using codeigniter 3.1.0 and HMVC

I looked at this Failed to access the controller in a subfolder , but when turned on it does not display the controller by default.

<?php (defined('BASEPATH')) OR exit('No direct script access allowed');

Perhaps this is possible, but do you really need to?

I can see the meaning of using ...

application > modules > catalog > controllers > forum > Category.php

But I see no reason to use ...

application > modules > catalog > controllers > forum > categories > Category.php

This happens too deep to put things in their small boxes.

...

application > modules > forum > controllers > categories > Category.php
