convert

Queues the one-time conversion of a blueprint, unless it already loads without converting. The blueprint is copied into a reserved world, the server loads it and saves it on unload in its own format (Paper dimension storage, the Minecraft 26.1+ vanilla layout, or current level data on older servers), and the saved result replaces the blueprint off the main thread. A failed conversion leaves the blueprint as it was, and its copies keep converting as they load. Imports replace blueprints whole, so updated content converts again.
