Additional context

Thanks again for the additional information, I’m pretty sure the fix in 7da9664 should resolve the path issue you’re running into.

The division symbol deprecation warning should be gone with the changes in 6296251. It’s a little more complicated than simply upgrading the generated sass file, other processors such as libsass don’t implement math.div ye. Luckily the chunking logic that was there for performance reasons back in the day could be removed.

In the future, creating a separate issue for something totally unrelated is usually the way to go to keep discussions on track ✌🏼

If you could test both of these by installing directly from GitHub, that’d be great! ❤️

npm install cascornelissen/svg-spritemap-webpack-plugin#master
