Hi,
I tried creating a new "ribbon world" map using various mods as well as "enable all planets" (has dependencies for all planet mods), but I've since disabled ALL mods except base, Space Age, and Lignumis (but it also happens with "default" maps).
In the "preview" when creating a new map, I have all (stone, coal, iron, copper) deposits. But once I jump into the game, all coal, iron, and copper deposits on Nauvis are replaced with peat, and gold spawns as well. I can't figure out what causes this.
Best Regards
