Any chance of of bug fixing the demo so that at least the castle can be visited? If it's intentional atleast have the game give a proper response instead of an error message of there being no map32.json.
i think he didn't remove the map by right way , if he just delete the json from data then it may happen error due to the link broken and database didn't catch up the update.
you can copy and past map017 and rename it to map032, that JSON is the game looking for.
