I am talking about this mod: https://mods.factorio.com/mod/angelsindustries
When it is active white loader graphics is fine but yellow graphics is getting replaced (I assume with Loader Redux). I didn't test other loaders.
I am not sure who should provide a fix for this but I've decided to ask here first.

I'll play around with it, see what's going on.

Also would be helpful if you could list what mods you have active. :D

Edit: I see the same issue. Now to explore what's happening and if I can fix it on my end like I did with Loader Redux...

I have a fix. Now because I noticed a few other issues and I think I fixed them I have to run the test matrix. I'll push a fix when I'm done with that, maybe an hour or two.
