Hi, apologies for breaking your tweaks mod.
Indeed, my new update refactored mod-specific stuff out of data-util
. I actually plan to remove steel_to_titanium
in another update very soon, (Titanium was my first real mod and I've improved my library functions since), but you should be able to use util.replace_ingredient("<recipe-name>", "steel-plate", "titanium-plate")
for the same effect.
I am not planning any further similar changes that would break dependency on data-util
again.
