CI 3 & HMVC Issue

I made a little change in the MX Loader and it worked.

/** Load a module model **/
public function model($model, $object_name = NULL, $connect = FALSE)
{
if (is_array($model)) return $this->models($model);

($_alias = $object_name) OR $_alias = basename($model);

if (in_array($_alias, $this->_ci_models, TRUE))
return $this;

/* check module */
// this-> list($path, $_model) = Modules::find(strtolower($model), $this->_module, 'models/');
list($path, $_model) = Modules::find($model, $this->_module, 'models/');
