The page says adding it to an existing save allows generation in new chunks, but when i go to explore new chunks to generate them, they generate the custom islands and cliffs, but the islands look like normal fulgora islands with no decoratives or enemies, just the cliffs from this mod.
It works fine if i go into the editor and regenerate the surface, but then achievements are disabled and i lose my base. Maybe its not meant to work on existing surfaces and i misunderstood the main page or something idk, thought i would make a thread about it just in case because this mod is really cool.
