The browser will always return a 404 for `style.css` when you run `yarn start` because it uses webpack to inject styles directly into the page. The file in your dist folder is probably one left over from running `yarn build`. The specific error you’re seeing seems new. This workaround may work for you: [Enable CSS build when watching · Issue #1826 · roots/sage · GitHub](https://github.com/roots/sage/issues/1826)
