A session on $_SESSION

Ok... I'd be inclined to want to label this as a bug in the framework.

Here's one work-around:

In \App\Config\App.php, changing $sessionExpiration to any (probably large) non-zero constant:

Code:

/**
* --------------------------------------------------------------------------
* Session Expiration
* --------------------------------------------------------------------------
*
* The number of SECONDS you want the session to last.
* Setting to 0 (zero) means expire when the browser is closed.
*
* @var integer
*/
public $sessionExpiration = Vars::COOKIE_SESSION_VALIDITY;    //  !! 0 causes random, intermittent session loss
