The author of the mod marked it as deprecated
https://mods.factorio.com/mod/skewer_shattered_planet

CPU_BlackHeart - The mod is currently discontinued as it is my first mod I've made for Factorio but it massively needs an overhaul.

Good to know, it's currently an optional dependency to this pack, so no changes necessary to the pack itself, but I'll update the description to notate that. Hopefully they do circle back to the Shattered Planet mod, since it seemed pretty interesting, conceptually speaking

They've put the mod back to work.
You can probably delete the review so that it doesn't mislead.

Thanks for the notice, I'll keep this up for posterity, but events like this are part of the reason I'm slow to make certain kinds of updates/changes lol

Updated the title and removed the deprecated tag from the planet in the description
