Hello,
You should put Space Age as an optional dependency.

space age is required because the manufacturer is intended to be a parallel with the em plant, foundry, etc. it doesn't really have a reason to exist in the base game so is not in even though it technically could, I have no desire to add it, if you or anyone else wants to feel free to use any of my code and credit hurricane for the building graphics.

Alright why not but if we start from the principle that we play on the base game with mods then that changes things.

but thanks.
