Description (last modified by dd32)

In some cases there are some problems with wp_schedule_event. It schedule the event, if we use wp_next_scheduled, it gives a timestamp, but using WP Crontrol, it doesn't appear there.
Below some code to reproduce it.
If you click on the button, it will schedule 500 events. Wait a bit, that 100 or so are processed (look at the logs or use WP Control to check). Then click again. The logs show that they should have been schedules, there is a timestamp and the transient is created. But it's not really scheduled, it doesn't appear with WP Control, and the transient is not deleted (for the 2nd round)

if (!class_exists("NSM_Test_Cron")) {

    class NSM_Test_Cron {

        function __construct() {
            add_action('admin_menu', array($this, 'my_custom_button_menu'));
            add_filter('cron_schedules', array($this, 'cron_schedules'));
            add_action('nsm_test_cron', array($this, 'nsm_test_cron'));
        }

        public function cron_schedules($schedules) {
            if (!isset($schedules['nsm_60_seconds'])) {
                $schedules['nsm_60_seconds'] = array('interval' => 60, 'display' => '60 Seconds');
            }
            return $schedules;
        }
