I've got this
Failed to load mods: __science-spread__/data-final-fixes.lua:66: bad argument #1 of 2 to 'pairs' (table expected, got nil)
stack traceback:
[C]: in function 'pairs'
__science-spread__/data-final-fixes.lua:66: in main chunk
Mods to be disabled:
• science-spread (0.4.0)
When trying to combine these mods together:
Tech tree plus + Krastorio Spaced out + Fusion lab + Fusion machines + Science spread + Space age stuff
Disabling my mod yielded the same result. Disabling everything except "Science spread" still results in a crash.
I would suggest you tell this to the developer "Frontrider" and disable that mod (science-spread) untill it gets fixed.
