Cannot assign string to property MediaWiki\Extension\CampaignEvents\Event\EventRegistration::$meetingAddress of type ?MediaWiki\Extension\CampaignEvents\Address\Address

Uhhhhh of course it can't, I changed the format of the property. But I also bumped the cache version key in the same patch. Why is it trying to unserialize a value with an older version key??

450 seen for the last 24 hours. These would eventually fix themselves as the cache expires, but the cache in question has a TTL of up to 1 week, and that's too long to just wait it out.

Well, technically, for the last ~5 hours, as it's meta-only and wmf.8 reached group 1 ~5 hours ago. Also, this would get worse for group 2, hence making it a train blocker.
