Hey there. I really enjoy both this mod and the Artisanal Reskins mod, thanks for all your work!

Unfortunately, I get this error after I bumped the version of a few mods, and I think it's Artisanal Reskins: Angel's Mods (2.0.2) and Artisanal Reskins: Compatibility (2.0.4) that break in combination with Extended Angels. This is the error:

Failed to load mods: extendedangels/prototypes/buildings/refining.lua:227: attempt to index field 'layers' (a nil value)
stack traceback:
extendedangels/prototypes/buildings/refining.lua:227: in main chunk
[C]: in function 'require'
extendedangels/data.lua:15: in main chunk

Mods to be disabled:
- extendedangels(0.5.1)

This is the source line:
data.raw["assembling-machine"]["ore-floatation-cell-4"].animation.layers[2].tint = {r = 0.70, g = 0.50, b = 0} -- Yellow

The previous line does the same for "ore-crusher-4", so I'm guessing that the new sprites in 2.0.2 of Angel's reskins doesn't have a layer[2] for the "ore-floatation-cell-4" any more?

Would you make me a save with all the mods you have enabled (except Extended Angels) and link it here? This doesn't happen in any of my test worlds, to include bare-bones EA test world + AR, so there's something else at work that I'd like to check.

Rather, this only happens with the Angel dev branch, because the Angel dev branch is currently porting the high-res sprites from AR into angelsrefining. Are you using the dev branch?

Ah, I think I found the combination. The dependency chain is such that extendedangels can execute after reskins-angels if you're using the Clowns mods:

Awesomesauce, thanks! I'm indeed using the Clowns mods. I'll provide my mod list via a save next time, sorry.
