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"
