Updated the plugin to latest Sponge changes and it is acting as a world generator modifier now instead of a plugin that load the worlds manually. Because of that you now need a world manager like Project Worlds to create the worlds and you need to set the appropriate world generator modifier when creating the worlds:
- For the Alpha 1.1.2_01 generator:
nostalgiagen:alpha_1.1.2_01 - For the Beta 1.7.3 generator:
nostalgiagen:beta_1.7.3
See the main post for an example how to create a world using a world generator modifier. This has the advantage that you can now create mulitple worlds with the same generator.
