Data, Safety and Editions
Player progression, bases and world structures are persisted by the plugin's DataManager and PlayerDataManager. Base deletion has a base.delete.keep-player-data option; its default is false, so review it before deleting a configured base. Setup managers retain preview/undo state for structure operations, but an external world backup is still recommended before large layout changes.
The free edition is limited to five bases and one conveyor. License configuration uses license.key, endpoint and server-id. Never publish the license key. A failed remote check should be diagnosed through the license status command and server log rather than repeatedly reinstalling or deleting player data.
