Custom logout function not working

[eluser]adamp1[/eluser]
I know right away why it doesn't work, change

Code:

$logout = $this->session->sess_destroy();

To this

Code:

$logout = $this->session->sess_destroy();
$this->session->sess_create();

This is a common mistake everyone makes. Not 100% sure why it doesn't work the other way, I did know but forgotten now. I believe its got something to do with the cookie not being erased till next page load or something.
