Problem:
Electric furnaces which have no (inactive?) recipe can have modules inserted, they work for alien plates, but on level-up, all the modules disappear.

The reason this is looking like a game bug, is that I can't insert modules after the recipe is working - which agrees with the modules disappearing on level-up, they couldn't be inserted. It also agrees with the prototype explorer telling me the alien-plate does not allow productivity.

I have steel furnaces which show as accepting productivity for plate recipes, but the modules just don't work. I don't know if there's a mismatch there with how the game re-worked how modules work, but it appears my burner furnaces SHOULD allow productivity, they just... don't. The modules work for productivity in electric furnaces, and can be freely inserted and removed from steel furnaces (unlike where they can't be inserted for electric).

I'll probably post about it on the forums, cause it is an odd, new issue from 2.0.
