I keep getting this error message when enabling this mod:

Failed to load mods: mini-micro-settings/func.lua:142: attempt to index field '?' (a nil value)
stack traceback:
mini-micro-settings/func.lua:142: in function 'addMachinesToTable'
mini-micro-settings/data-final-fixes.lua:61: in main chunk

hopefully this helps to figure it out.

This one was a bit complicated, and there were actually multiple ways to trigger this exact bug. Hopefully they should all be resolved with v1.1.1

You might also need to update Mini Machines, Micro Machines, and possibly Reverse Factory, depending on which mods you were using that triggered the bug. It was likely either Micro Machines + Quality/Space Age, or Mini Machines + Reverse Factory without Space Age.

Everything seems to work fine now, nice work.
