Some stuff is useable with heat even tho it shouldn't
Unfortunately that's the price of dynamic generation - the mod only cares if a machine is powered by electricity. If I wanted to skip some out of place machines, I'd have to manually add compatibility for each of them, and even then it's easy to miss some.
I actually got an idea, what about instead of the overhaul, make a mod that adds something related to heat IRL, as well as some re-worked heating machines
Considering that my overhaul idea started moving away from the initial plan, I'll probably move the overhaul somewhere else.
As such, I could do some of those, although not all suggestions seem easy/possible to do, and I'd certainly need some help with textures :)
Regarding discord, just search on the factorio discord. Should show up as "Sylen - heating in progress"
