I hope this mod isn't dead, i find it really useful.

anyways, I'm playing with Space Exploration and for some reason stone bricks are exclusive to the vanilla furnaces and SE's Thermodynamics Facility.
the other recipes like iron/copper/steel plates work perfectly fine in the electric furnaces.

I have had the same problem. I might look into the coding of this mod later to see why.

I just realized that I have a mod that fixes multiplayer, not this one. That may be the problem.

a new mod is out fixing it.

Sesame_Slayer, which mod?

EDIT: Here it is: https://mods.factorio.com/mod/electric-furnaces-space-exploration-fix/discussion/6300159e29dd0a0d2169fc9c

thanks for the fix! I wonder if this fix would also affect burner inserter fuel bonus mod. It was stopping stone from smelting with solid fuel or rocket fuel..
