There seems to be an incompatibility between this mod and Flare Stacks with the recent update. Idk if ya wanna fix it or not.

So, this mod here https://mods.factorio.com/mod/Flare%20Stack

I have one more thing, K2SO is running into an error with the Molten Rare Metals texture.

Error loading mods
Failed to load mods: The given sprite rectangle (left_top=0x0, right_bottom=256x256) is outside the actual sprite size (left_top=0x0, right_bottom=64x64). If this is being used as an icon you may need to define the icon_size property.
See the log file for more information:
