Hello, I have noticed we have a research for molten metal productivity, but only basic productivity for tungsten recipes like plates and carbide, is it intentional, or is there a plan to add those higher tiers to the research of smelting tiers (and also infinite prod research)?

Love your mod nonetheless, it adds a step but makes it really fun to work with, and feels satisfying to get a reward for a more complex process

That is intentional since vanilla SA doesn't have any productivity techs for planet-specific resources. I had the urge to add it at first, but when I realized the above I decided against it.

Glad you're enjoying it!

No worries, it's still amazing, especially when you have a long-term mods like deep core mining, making those puny little patches catch up a bit with crushing
