classic FU misinformation moment

File-wise there's no such thing as "Scorched underground".

There are 4 underground layer files (with 4 variations each), roughly thematic to the planet they're in.
As well as 'underground detached' "biomes", if you could call them that. Places like slime caves, cell/flesh caves, mushroom caves, gnome village caves. Which spawn on top of said 4 layers randomly as directed by the terrestial.config file.

This mod adds these 2 "microdungeons" to all said underground-related files, with a custom "super rare" distribution parameter made by yours truly.

And no, they were not present in there previously, I believe, since at least beta, if were present at all. I had them all open in Notepad++ at one point and searched for "rocktunnel", "rockclimb", "terrainfeaturesrare", "rare" and got zero hits, so here you go.

I found these in the base game files. What exactly is the purpose of this mod? Someone on the FU Discord said that they're already available on Scorched planets. You just added them to the vanilla biome pool for any planet, I suppose?
