Hello, when I add a new particle such as "slideshow" to the Galaxy theme i get an error from the CSS that came with it.
An exception has been thrown during the rendering of a template ("CSS Compilation on file 'custom.scss' failed on error: Undefined mixin breakpoint: line: 18") in "@nucleus/page_head.html.twig" at line 18.
I am working locally so i can't provide a link I'm afraid.
Any help would be appreciated.
