Navigation Menu disappears on update to 5.16.0
On updating to 5.16.0 our Navigation Menu disappeared from the top of the screen. Was still able to access other screens e.g. contacts via the dashboard and the civicrm/admin menu. Some screens (such as "Configure your dashboard") brought up an error saying "couldn't connect to network". When viewing a contact a white space where the navigation menu would normally live was at the top of screen. Other than that all I could see was the normal Drupal 7 Admin menu (normally hidden when viewing Civi). I've managed to roll back to 5.15.1 for now. Not sure if anyone else has experienced similar.
