Clone a world

To clone a world you can use the /world clone <world> <key> [template] command.
This command creates a copy of the specified world, allowing you to work on a separate instance without affecting the original.

The template option defines whether the cloned world should be regenerated or an exact copy of the original world.

Example on how to create an exact copy of a world (1:1):

/world clone worlds:my_world my_world_copy

Example on how to clone a world's generation settings (no region data, scoreboards, player data, etc.):

/world clone worlds:my_world my_world_copy template
