This Mod seems to overlap with Planet Paracelsus weirdly. Zinc still spawns on Nauvis, but it basically becomes completely useless and thus softlocks you. Plates and stuff still are available, but only when using Paracelsins Zinc Plate Production Line, which is not even close to being available at the start of the game.

I have not gotten around to making any of the planetfall mods compatible with space age as it requires a lot of work even to just get familiar with the multi-planets and the tech tree modifications. I will let you know when I do tackle space age!
