If your server is resetting the save each restart, you need to configure the server to use the YlandFile of your save.
To do this, you have to:
- Stop your server.
- Go back into the DSConfig.json configuration editor.
- On the session type dropdown choose YlandFile.
- On the session data dropdown choose the world you're using.
- Click save, and restart your server!
It should now no longer reset each time the server restarts.
