Both the Arig infinite techs (quartz productivity and heavy glass productivity) require metallurgic science from Vulcanus, as well as Arig's compression science. Can we get one of them that just requires Arig? Heavy glass, maybe. Or add a new one that's just Arig (maybe container capacity, if that's easy to implement - seems like a good choice for the science of compression).
The planet is reasonably balanced, so I'm not looking for anything super-strong here. I just want to have something I can sink extra packs into if my other off-world sciences have run out. I don't like how my compression packs stack up forever without any way to use them, if there's ever a problem with my Vulc build.
And to avoid thread-spamming you, I notice the same thing is true of your Hyarion mod with Fulgora science, and your Tellus mod with Gleba science. I haven't played those worlds yet, but I assume I'll have the same annoyance there. I assume this was an intentional decision on your part, but it's the one bit of Arig that I've disliked so far, and so I'll suggest that you might want to change this decision in general. I don't need the infinite tech that I dump extra packs into to be good, but I'd like it to exist. Everything ought to have some potential dedicated outflow somewhere.
