Basically doesn't work with other types of fuel source. seeds and other mods probably.
Disco Research incompatibility
Bio Industries and other Tree / seed / sapling mods

That's... odd. All this mod does is assign fuel_glow_color values to anything it finds with a fuel_value. Yet this error suggests that one has been assigned to some item without a fuel_value. I'm not sure how that could happen; maybe another mod removed the fuel_value later in the load order?

Its really not, @FlamingCarrot, mods use dummy fuels just to make things work script-wise from control etc, those fuel items cant be obtained by player any normal way.

For this error ive made possibly FIXER
