So I created a now world for the Cosmic Upgrade and when it loaded, the entire world was made of abyssalite!
After I took the screenshot, I activated sandbox mode and reveled the entire map, the points of interest generated correctly but the rest of the map
was filled, top to bottom, with abyssalite.
I used the default game options and I didn't mess with the files, so I have no idea what caused this to happen.
I made another world to see if it would happen again, but it generated normally.
I attached the save file if you want to check it out.
Steps to Reproduce
I just started a new world, I don't know what caused it.
This issue has not been confirmed by a developer yet.
