possible typo in rooms_unit_admin.inc

While reading code ... I noticed
rooms_unit_admin.inc line 386

 else {
    $units[0] =  $form_state['rooms_unit'];
    $unites[0] = entity_ui_controller('rooms_unit')->entityFormSubmitBuildEntity($form, $form_state);
    $units[0]->changed = time();
  }

$unites should be $units? (no other occurrence of $unites elsewhere in Rooms project)
