Subject: [PATCH] Provide option to use a versioned world folder for testing
|
|
|
|
This should not ever be used in production!!
|
|
|
|
This setting is intended for testing so you can try out converting your world
|
|
without actually modifying the world files.
|
|
|
|
This will add some additional overhead to your world, but you're
|
|
just testing anyways so that's not a big deal :)
|
|
|
|
Will store in a folder named after the current version.
|
|
|
|
PlayerData and Data folders are copied on server start, so there
|
|
may be some delay there, but region files are only copied on demand.
|
|
|
|
This is highly experiemental so backup your world before relying on this to not modify it
