getting a crash with Krastorio 2 due to the way it uses Uranium Magazines. here is the info from my crash. I only got it after updating to 1.4 yesterday

https://mods.factorio.com/mod/Krastorio2-spaced-out?from=search

Failed to load mods: Error while loadig recipe prototype "uranium-rounds-magazine-qp-normal" (recipe): Recipe has invalid main product uranium-rounds-magazine. The Product does not exist in the recipe product list. Modifications: Quality Processing > Krastorio 2 Spaced Out

Mods to be disabled:
quality-processing (1.2.3)
Krastorio2-spaced-out (1.4.18)

The issue seems to be that Krastorio 2 replaces the "uranium-rounds-magazine" with "kr-uranium-rifle-magazine" in the ingredients and results of all recipies, including those generated by this mod. But the field "main_product" is not updated, leading to this mismatch.
Could you report this bug on the mod page of Krastorio 2?

absolutely

Is this k2so bug a one liner to fix, like changing the uranium ammo recipe or something? I would love to try this different approach to quality because normal recycling and space casino builds are getting stale, but I'm already 130h into the k2so game...

The solution should be taking the "uranium-rounds-magazine-qp-<quality>" recipes and setting "main_product=kr-uranium-rifle-magazine".
