Attempting to load Fire Lights together with https://mods.factorio.com/mod/deadsun causes a crash on launch. (Only mods enabled are Fire Lights, Sun is Dead, and Space Age.)
Failed to load mods: fire-lights/data-final-fixes.lua:26: attempt to index local 'light' (a number value)
stack traceback:
fire-lights/data-final-fixes.lua:26: in function 'process_character'

I saw these two mods and thought they would go really well together.
