Npm run dev compiles and works fine, npm run build doesn't - why?

Working on a build and while npm run dev compiles fine, the npm run build does not.

I get the following errors:

Conflicting order. Following module has been added:
│ * css …/node_modules/@roots/bud-support/lib/css-loader/index.cjs??css!../no
de_modules/postcss-loader/dist/cjs.js??postcss!../node_modules/resolve-url-load
er/index.js??resolveUrl!../node_modules/sass-loader/dist/cjs.js??sass!./views/u
i-kit/text-and-media-repeater/text-and-media-repeater.scss
│ despite it was not able to fulfill desired ordering with these modules:
│ * css …/node_modules/@roots/bud-support/lib/css-loader/index.cjs??css!../no
de_modules/postcss-loader/dist/cjs.js??postcss!../node_modules/resolve-url-load
er/index.js??resolveUrl!../node_modules/sass-loader/dist/cjs.js??sass!./views/u
i-kit/text-image-banner/text-image-banner.scss

couldn’t fulfill desired order of chunk group(s)

Has anyone seen anything like this before?
