It's pretty much the title. Updated mod version to 1.0.0 and all previously crafted sacrifices have to be done again.
This happened before at least once, but I wasn't sure whether I was hallucinating that. The first time it was before sacrificing Oil springs, so it's more of a deal now. :/
I still have the savefile though, I'll just fork it and design a couple blueprints in the meanthyme.
