Compatibility issue with "factorio-deadlock-experiments". Looks like the issue is due to your productivity modules not having any "limitation" settings as the mod tries to append new recipies to this property here https://github.com/shanemadden/factorio-deadlock-experiments/blob/5fb334ed9997a2c1eee798495da21133772665e9/prototypes/directsmelting-final-fixes.lua#L15 and fails as its not possible to append to a nil.
