      The bug

      The changes that you made to dimensions will not be saved. If you're on a singleplayer world you must reload your world, servers require rebooting them. This is exceptionally inconvenient, especially for testing environments.

      How to reproduce:

      1. Download the attached datapack with a custom dimension mc-187938.zip
      2. Join the world
        → The custom:foo dimension appears when typing /execute in
      3. Modify or rename the custom dimension
      4. Run /reload
        → The dimension still has the old name and properties
