Great idea. I have a question: does your mod also work on a saved game? Because I installed it, I uploaded my map, but I can't find any deposits.
Thanks

I don't believe it does. I think the surface (what factorio treats different planets as) has its resource generation functions defined at creation time. It's possible you could use the console and delete and regenerate the surface (if you didn't mind loosing all progress on fulgora) and that might work. When I have time I can review things and see if it's possible to make it so it will work.
