On Steam, Factorio v2.0.76, with Nullius v2.0.9, with Artisinal Reskins: Nullius v0.1.3 I try to load this mod v2.1.0 and get the following error:

Failed to load mods: __nullius-visual-tweaks__/scripts/electric-furnaces.lua:47: attempt to index field 'layers' (a nil value)
stack traceback:
    __nullius-visual-tweaks__/scripts/electric-furnaces.lua:47: in main chunk
    [C]: in function 'require'
    __nullius-visual-tweaks__/data-updates.lua:2: in main chunk

Looks like the conflict is explicitly in Artisinal Reskins: Bob's Mods v2.3.8

Since Nullius + Artisanal Reskins: Bob's Mods also affects a few of the same things such as the look of furnaces, I'd imagine that it's incompatible with this mod without changing any settings. If you'd still like some of the changes, you can try turning off Electric Furnaces and anything else that crops up an error in the mod settings to see if that helps.

I'm running the same versions of Nullius, Artisinal Reskins: Bob's Mods, and this mod but with Factorio 2.0.77 and I don't have this error fwiw.
