In data.lua you have some icon definitions. the lines with"= 64, icon_mipmaps = 4," should be added after every "icon = " line otherwise a startup error will be generated.
I assume it only happens when used in combinations with other mods (I use 300+)

Changing every line like for example:

            icon = "__base__/graphics/icons/signal/signal_yellow.png",

into

            icon = "__base__/graphics/icons/signal/signal_yellow.png",
            icon_size = 64, icon_mipmaps = 4,

fixed it. The startup error is very misleading. I could only pinpoint it to your mod because you used signal_yellow.png in particular and no other mod was using it.

Okay, just tested this and it doesn't affect my testing, so I'm going to drop it in v0.0.6 in a moment.

Thanks. Bear in mind that every icon needs it, even the one that's dynamically generated. Ask me how I know :)

I get the above error:

I get it when I load two mods in total: "Blueprint Variables" and "Angels Refining". If I only load "Blueprint Variables" or only load "Angels Refining" I do not get any error.

This requires a hotfix since it makes your mod unusable at the moment. I hope you dont wait for other cool features to be finished until you release this hotfix. Meanwhile I have to kick out your (very actually very cool and handy) mod.

Due to the bug I had to exclude your mod from my mod pack https://mods.factorio.com/mod/schmitts-modpack I hope you fix it.

I've seen this, and plan on fixing it, I just haven't had the time yet

No sweat. Just wanted to keep you posted. Nobody dies because of this bug ;-)

Fixed in 0.1.2, thanks for the encouragement DE_Schmitt.

Wonderful! Thus I have reintegrated your mod into my modpack https://mods.factorio.com/mod/schmitts-modpack :-)
