A transfer or private zone request started a world server for whatever map ID it named, and for as many instances as were asked for. A new instance now needs a row in the ZoneTable for its zone, and no more than max_instances (masterconfig.ini, 256 by default, 0 for no limit) run at once. The character select has no row and is always started. A request that gets no instance is logged and dropped. Before, the handlers went on to use the missing instance.
