I do not like having to import so much stuff into the planet. Really the only item it needs on the terrain generation is Fulgora Scrap piles instead of just the ruins.

I second this, seriously. There is no way this can possibly be fun without a way to get resources. War is expensive. I see that it has fulgora ruins I guess but that's not enough. I'd rather go to Nekohaven and have to import uranium.

Screw it. I made a patch: https://mods.factorio.com/mod/planet-hexalith-fulgora-scrap

There is a bug where some of the scrap patches have stupidly large amounts of richness while others are normal richness but good luck beating this planet even with that "advantage". Also, my mod by default sets Hexalith magnetic field to 99% but you can change it to whatever you like in the settings menu. Also, I added holmium ore deposits to spice things up a bit and to make it more different from Nekohaven but that feature is disabled by default. And disabling it also prevents any auxillary holmium ore data from being loaded to make it possible to avoid unwanted bloat.
