Switch to Namalsk, Deer Isle or another map

A community map is a mod plus a mission folder. Installing the mod alone gets you a server that starts and then immediately fails, because it is still pointing at the Chernarus mission.

1. 1Install the map mod from the Workshop as usual.
2. 2Upload its mission folder into mpmissions.
3. 3Open serverDZ.cfg and set the template to that mission folder name.
4. 4Start the server and watch for the map name in the console.

class Missions {
    class DayZ {
        template="dayzOffline.namalsk";
    };
};
