Excuse, does this only work for the vanilla recipes? It seems recipes from K2 or the Space Exploration mod are not working.

At this point its not yet stable for K2 and SE and other overhauls....
In 4.2 I added broader support for these but the loading times skyrocketted.
In 4.3 I got loading times down by 60% but had to lose some compatability.
Stay tuned, after a few updates for optimizations and performance I'll try to add modded support again without the lag

I am using this mod with Space Exploration + Krastorio 2.
Do you have any plans to add productivity, for the exotic materials that SE and K2 adds (vitamenlagne, rare metals, hydrogen chloride, nitric acid , and the ingots, etc...)
Also the (Science pack productivity research) technology, is not working for the advanced science packs that K2 adds.

i have plans to do all of this, but every time i add support for one mod, it breaks others and creates crashes and issues, so i dont know when i will be able to go back to adding more mod support. I will try to add new techs/prods etc in 5.1, but for now 5.0 still isnt stable. If you want to, i'd take suggestions for specific techs/recipies/effects/etc if you share a list of ideas or even some code changes to github... These above recipies and items you listed are on my list of things to do, I'll let you know when i revisit them, hopefully soon
