I have a similar issue. When I try to load this as a multiplayer LAN world, the loading bar fills all the way, then after a few seconds, the game crashes. This also happens when I loaded the file as a single player world.

Cool! I think a mod should be created to add new tiles to make a new "planet". And more tech. And more stuff...

Yeah, that would take a lot of effort, but could work really well with this mod!

Sounds fantastic!!! You should come up with more loot though. Maybe you could choose between searching dungeons for loot and Relic Science Packs (used to research Relic-related tech) or using messier, dirtier, but extremely effect tech. Everything the Creepers would hate. ( https://www.factorio.com/...

Can't wait to see what this mod becomes!
