A small add-on for Muluna that adds new mooncrete and refined mooncrete tiles, as well as an alternate asphalt-from-bitumen recipe if you have that mod installed.
Mooncrete gets unlocked with advanced stone processing, which requires space science and metallurgic science, while refined mooncrete is already unlocked with alumina processing. I think it's own tech depending on all required techs for the ingredients would be nice, so one can make mooncrete when everything is available.
Yeah I definitely didn't put as much thought into that aspect as I should have. I'm currently on a break from working on mods but I'm planning to redesign this a bit more intuitively in the near future, and your suggestion is definitely on the list of things I'm changing.
