Server scripts are working on windows servers but not on ubuntu servers.

How to reproduce:

1. Load the 1.18.2.03 versions of the servers.
2. Extract Charn.zip into worlds.
3. Import server.properties and valid_known_packs.json.
4. Start the Server and join with a client.
5. On windows you get spammed with "script loading".
6. On ubuntu nothing happens.
7. You can check if the addon loaded by executing the command "/function sudokuGive"
