@SolarDragon:
- 1. Since this adds new biomes, I'd imagine the worst that would happen, if uninstalled, is that various planets that you've visited while the mod was installed become inaccessible until either the mod is reinstalled or the planet files are deleted from your universe folder (which would reset those planets).
- 2. Assuming no other mods were present that add more secondary biomes (such as Frackin' Universe), I'd guess that they'd spawn quite frequently, since they're competing with vanilla Starbound's secondary biomes for spawning, and also since there's a lot of these village and dungeon biomes in the pool. (If you feel as if there's too many, then perhaps the Village and Dungeon Sub-Biomes mod would be a better fit? That, or installing other mods that add secondary biomes should help.)

1. Is this safe to uninstall mid-playthrough
2. How often do these spawn? (I don't want these to spawn in every biome I encounter as that's a bit too much)
