The object.parent foreign key (ref_parent, ON DELETE CASCADE) is dropped in World Boot Plan 2.4: static zones and buildings leave the DB, so rows under them get negative parents that no object row holds. deleteObjectTree deletes an object and every row below it by parent in one transaction, which is what the cascade did. Used by the building, guild, mob, NPC and zone delete paths (city destroy relies on it for the city, NPCs and mobs). Value changes: none; the same rows are deleted, and the FK is still in place until the 2.4 migration runs. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
