Fatal Error

1.7.4 fatals on my local test site after upgrading from 1.7.3. I didn’t dive deep, but this appears to be shipping related, and my test site is all virtual products, if that helps.

Uncaught TypeError: Cannot assign null to property WPDesk\FlexibleSubscriptions\Utils\SessionContext::$shipping_methods of type array in /srv/htdocs/wp-content/plugins/flexible-subscriptions/src/Utils/SessionContext.php:14
