Hey there! Research Productivity 1 requires Promethium science packs, which require Promethium asteroid chunks - which require going to space, obviously

Would it be possible to use the fix AlchavX used here https://mods.factorio.com/mod/SpaceAgeWithoutSpace/discussion/6740d73ab7e63606d0b93360 or (more preferably) add a recipe to create the chunks/change the science pack recipe?

Love the mod, this solved a lot of my problems with space age <3

I just added a new recipe for making promethium asteroid chunks. If it seems too expensive please let me know as I have been playing space exploration and my sense of price for vanilla items is a bit off.

Glad you are enjoying the mod :)
