Scheduled events disappear from events queue

My solution for now is check every hour if it is running and if not reschedule it. I also remove this in deactivate etc.

wp_schedule_event(time(), 'hourly', 'my_restart_schedule_if_failed');

function my_restart_schedule_if_failed() {
    if( !wp_next_scheduled( 'my_scheduled_minute_job' ) ) {
        wp_schedule_event( time(), 'one_minute', 'my_scheduled_minute_job' );
    }
}
