Artisanial Reskins Library causes a crash when loading with this mod enabled, Space Age being installed poses no issue with this error, this is using the mods latest version at 1.1.5
Failed to load mods: tiered-gas-generator/data.lua:79: attempt to call field 'adjust_alpha' (a nil value)
stack traceback: tiered-gas-generator/data.lua:79: in function 'add_labels' tiered-gas-generator/data.lua:100: in main chunk
Seems like the artisanal mod has removed this function. I've uploaded a quick fix for that. If it does look weird to you, you can edit line 80 in data.lua and set the alpha value to your liking (the 0.75 one).
