The error message claims 'failed to load mods: error while running setup for recipe prototype "foundation" (recipe): Recipe is in 'crafting' category but has a non-item ingredient 'fluoroketone-cold' (fluid).

Guessing this means it's in handcrafting despite needing a fluid and thus broke but not sure. I don't believe I have any other mods enabled that should affect the foundation recipe.

Update is available to fix. Not sure how this wasn't an issue in testing, but I'm 99% sure it's fixed now.

Still playing with it, I see that firearm magazines and cannon shells can no longer be produced in the foundry in my existing save. Is there a setting I'm missing or?

That one I can't see any reason for, but I've changed part of the load order to possibly fix. Are you playing with Age of Production or other mods?
