Codeingiter & HMVC Unable to locate controller if in 2 level sub folder - codeigniter

Question

If I place a controller in a 2 level sub folder "categories" will not locate 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
Question is it possiable to modify MY_Router.php so can locate the folder correct and not effec any thing else.
I am using codeigniter 3.1.0 and HMVC
I have looked at this Unable to access the controller in subfolder but when enable it does not display the default_controller.
<?php (defined('BASEPATH')) OR exit('No direct script access allowed');
/* load the MX_Router class */
require APPPATH."third_party/MX/Router.php";

/** Locate the controller **/
public function locate($segments)
{
$this->located = 0;
$ext = $this->config->item('controller_suffix').EXT;
/* use module route if available */
if (isset($segments[0]) && $routes = Modules::parse_routes($segments[0], implode('/', $segments)))
{
$segments = $routes;
}
/* get the segments array elements */
list($module, $directory, $controller) = array_pad($segments, 3, NULL);
/* check modules */
foreach (Modules::$locations as $location => $offset)
{
/* module exists? */
if (is_dir($source = $location.$module.'/controllers/'))
{
$this->module = $module;
$this->directory = $offset.$module.'/controllers/';
/* module sub-controller exists? */
if($directory)
{
/* module sub-directory exists? */
if(is_dir($source.$directory.'/'))
{
$source .= $directory.'/';
$this->directory .= $directory.'/';
/* module sub-directory controller exists? */
if($controller)
{
if(is_file($source.ucfirst($controller).$ext))
{
$this->located = 3;
return array_slice($segments, 2);
}
else $this->located = -1;
}
}
else

It might be possible, but do you really really need to?
I can sort of see the sense of using...
application > modules > catalog > controllers > forum > Category.php
But I don't see the point of using...
application > modules > catalog > controllers > forum > categories > Category.php
That is going a little too deep for the sake of putting things into their own little boxes.
Personally I would make the Forum a module and have...
application > modules > forum > controllers > categories > Category.php
