Hi
I met some error. In the Electric Furnaces there is an option to disable some of the recipes. In particular, I found the electric stone furnaces useless and turned them off. After that Flare Stack could not boot, tk. didn't find a recipe "electric-stone-furnace"

Can i suggest doing an additional check in the

if mods["Electric Furnaces"] then
eincinerator.ingredients =
{
{"electric-stone-furnace", 1},
{"iron-gear-wheel", 5},
{"electronic-circuit", 2},
{"pipe", 5}
}
end

If I understand correctly Electric Furnaces/settings.lua

{
type = "bool-setting",
name = "electric-furnaces-stone-steel",
setting_type = "startup",
default_value = true,
order = "a"
},

this is the variable that controls the disabling of the recipe for "electric-stone-furnace"

Just go into the recipe.lua for this mod and change the electric stone furnace to something else, or comment out the part that adds the electric stone furnace if you have both.

This problem is still present, I've created a pull request that fixes it on your GitHub. Please check.
