Fallout from T217146: ConfigException from line 339 of /srv/mediawiki/php-1.33.0-wmf.19/extensions/EventBus/includes/EventBus.php: EventBus::getInstance requires a configured $eventServiceName, which was an issue with job scheduling, and the rename jobs proceed by rescheduling themselves for the next wiki when they are finished. So everything should be in a clean state, just needs to be scheduled again. Although maybe we should wait for the patch to fixStuckGlobalRename to avoid getting fake unconnceted accounts again.
Please, notice that this rename (Rauman Kaupunginteatteri → Petteri Kangas) took about 20 minutes to complete. Even though it was approved at 12:52, every local account was still in queue according to rename progress special page. The rename actually started at around 13:05 when only fi.wiki was marked as done, and the process slowly ended in the next few minutes.
