as the title would suggest, the bonus to smelting is not applied to the industrial furnace. (upon testing, neither is the steel productivity research, but that's a core game issue). is this a bug, intentional, or something specific to the (many) mods i've got?

There is no "industrial furnace" in base or Space Age or provided by this mod so I would assume the issue is in whatever mod provides it.

so turns out it's from AAI. had that mod running so long i forgot it wasn't base game...

guess i'll need to use something to tweak the productivity to make those buildings worthwhile
