Trying to get property of non-object

Yup. The wierd thing is that I have a very similar function in a different model which works completely fine. The constructor for both Models are identical:

Code:

function __construct() {
        parent::__construct();
        $this->load->library(array("session", "form_validation"));
        $this->load->helper(array('url'));
        $this->load->model('NPCModel', '', TRUE);
        $this->load->model('PlayerModel', '', TRUE);
    }

The db is loaded automatically and works fine on my other pages...
