12.849 Error ModManager.cpp:1758: Failed to load mod "Igrys": __Igrys__/Scripts/Recipes/EnhancedSciencePacks.lua:46: attempt to index local 'item' (a nil value)

It's the "Super Farm" (mod-id: fruit) mod used by Planet Woodoria that has that null it seems. Still should be checked for.

see https://mods.factorio.com/mod/Igrys/discussion/687a2e8b86d9b798df20c19e

I changed that locally, but I don't know if that's a good idea or if it has sideeffects... (I'm still neither on Igrys nor Woodoria...)

I believe the root cause is this: https://mods.factorio.com/mod/fruit/discussion/687a2df0e75fcfdf30f29b71 but I don't know how to fix this since I don't know enough about the lifecycle of Factorio mods... (data, data-update, data- final etc.)

Yeah, items 'existence' should not be registered past the data stage, their bug, lol.
Should still nil test first before access though on something that isn't guaranteed to not be nil.

Adding a null test in the newest update, from the stef77 pull request. Thanks
