I don't know if this is intentional or not, but compared to the regular assembling machine, this one is missing the following crafting_categories

{ "pressing", "metallurgy-or-assembling", "organic-or-hand-crafting", "organic-or-assembling", "cryogenics-or-assembling", "crafting-with-fluid-or-metallurgy" }

not intentional. I also noticed few recipes missing during my playthrough. But when i was rewriting this mod i just copied all crafting_categories from assembling machine 3 from base (aka vanilla), because it was easier than just finding what was changed. But i also noticed now when playing with space age enabled that rocket fuel cannot be crafted with this machine. Its weird.
So i will need to find where these categories come from. Probably Space age add them to assembly machine? if so i need to only enable it when space age is enabled.

I will definitely look at this, but i am usure when i will have some free time to do it.

Hopefully its fixed.

Looks like it's fixed, thanks :)
