I expected the datapacks in the world to work.

But instead the world opened datapacks zip files and changed every "world" in a file name to the name of the world.

1. Open a realm
2. upload a world with a datapack (I saw this bug with vanilla tweaks' multiplayer sleep because it checks if a player is asleep in the over "WORLD")
3. then download the world to the computer and all the datapacks zip files should be unziped and everywhere you should see a "world" in the files name you'll see the name of the world instead.
