Factorio doesn't start with K2 and BZ zirconium https://i.imgur.com/wM5qcU4.png
did some testing and it boils down to only the two mods, I have the stacksize 200 feature of K2 disabled in settings if that matters
I am also having this error, as a workaround I disabled K2 mod stack size setting from no changes to a number from the drop down and it works while it gets fixed.
