Hi, I got this crash when trying out the mod:
Failed to load mod "Flat-Solar": Flat-Solar/data-final-fixes.lua:20: attempt to index field 'icons' (a nil value)
stack traceback:
Flat-Solar/data-final-fixes.lua:20: in main chunk
I was able to narrow down the cause to Artisanal Reskins: Library. I assume the crash is a result of that mod updating last month and changing some of its functions.
