Lignumis was fun and interesting to sort out all the designs to feed everything Peat, but after getting to Nauvis all of the changes made to Vanilla made it unfun. Green Science just became the most difficult one with no reward for all the extra work, at least triple the infrastructure just you can get red belts unlocked, just not worth the headache. Adding Wood and Steam science all across the tech tree made no sense and having to set up space platforms without Yellow and Purple Science even started yet just seems like a nightmare, not to mention without any other planet mods we are now up to 13 Colors of Science to fit around a tiny lab until you can get Biolabs Post Aquillo. I guess a Bot storm or a sushi science mess is the only option. Hubs/Malls across the planets are all whacked with this ridiculous requirement for Wooded crap added to yellow belt and inserter recipes for no sensible reason. If you want to Upcycle Turbo Belts for Tungstun on Vulcanus or Upcycle Super Computers on Moshine, congrats, a whole new wrench, suddenly you have to get wood to those planets in mass quantities since they dont already have them easily available. New planets are supposed to offer fresh new content that enhances the game, not break the game like this one is doing. I will admit the late game stuff looks interesting and again, Lignumis itself was fine, just all the Vanilla recipe and Tech tree changes ruined it. I wont be able to continue this one and I definitely cant add this to an existing save. I highly recommend reverting all the changes you made and keep the added planet mod experience what its supposed to be, additions to the game only, not redesigning it completely.
Good Luck
