Not all Websites are porcessed without --force-all-websites

I have a cronjob for the archive-thing

3 *     * * *   www-data        php /var/www/piwik.ibumedia.de/misc/cron/archive.php --url=http://piwik.ibumedia.de --force-all-websites > /dev/null

Now the --force-all-websites is marked as deprecated and I tried it without the parameter. But without the parameter not all of my Websites are processed and after a day the half of them show zero visits, pageimpressions, progression and a zero chart in all piwik pages. After forcing all websites all information is back.

Why is this?

Thanks for Help
