I'm trying to figure out what's causing my refine ratio to go way up (like 9 times its previous rate) in late game. I just saw it happen, but i have no idea why. I didn't buy any upgrades. I did buy the piscine mission, but i was watching to see if the ratio went up after i bought it and it didn't.
One minute i could trade in 5000 catnip for something like 110 wood, and the next minute i got 990 for the same 5000 catnip. I'm late game (pre-chronophysics but i have all the other science and upgrades).
So what is it that boosts it so much around this stage?
