Remove the Mod or Share Custom Saves Safely

How Client-Side Operation Protects Save Data

Disable Custom Worlds Advice runs strictly as a client-side tweak. Its only job is stopping your local game client from interrupting world launches with experimental confirmation screens. It does not alter your world save files, strip away experimental flags, or modify your data packs.

Because your save folder remains untouched, you can add or remove the mod at any time during an active playthrough without risking your worlds.

Sharing Worlds or Returning to Vanilla

If you want to send a custom world to another player, move it to a different profile, or uninstall the mod, follow these steps:

1. Close Minecraft completely before removing the mod from your mods folder, or open your saves directory to copy the world folder.

2. Move the world save to your unmodded profile or share the folder with other players as normal.

3. Open the save on the destination client.

Players who also have the mod installed will load straight into the shared world without prompts. Anyone opening the exact same save on an unmodded client will still load the world intact, with vanilla's standard experimental warning screen simply reappearing on launch.
