Der Dev AndyB hat mich darauf gebracht.
Genius!
Oft wurden Bots usw nicht ausgeführt.
Das liegt am Folgenden:

The solution: no bot message at 4:30 at clock etc:
AndyB says me:
Aktivitätsbasierter Trigger
or
Serverbasierter Trigger
in
Leistungsverhalten
is the problem I have no bot messages at this time.
Check in ACP and build a cronjob on the (root) server like this every minute:
*/1 * * * * php /var/www/your_site_root/cmd.php xf:run-jobs > /dev/null 2>&1
The reason is, if the activity is to small, the forum not runs some crons.
Thx to AndyB genius! (sorry, my language is german

The translator says:
Long-running and planned tasks are moved to the job system. By default, the activity in the forum triggers the execution of these jobs. This can be changed to trigger jobs regardless of activity in the forum, but additional setup is required. Note: If "server-based trigger" is selected, the server must be configured manually (eg with crontab or cron.d) so that the following command is executed once a minute: php /pfad/nach/xf/cmd.php xf: run jobs
