Takes https://mods.factorio.com/mod/ArachnidsFaction and adds more Space Exploration compatibility.

Features:
- Allows the planet surface be trimmed if there are arachnids nests.

Planet threat is not supported yet, so arachnids will spawn even on 0% threat planets. Support can be added in a future version of this mod.

NOTE: The mod should migrate a world from ArachnidsFaction without issues.
