Uncompiled files, like .scss, .sass, .less, .stylus etc overrides precompiled .css files with a conflicting name.
npm i larvitcss;
In your start script file, make sure all routes to css files are routed to the css-controller.
In the case of larvitbase, do something like this:
'customRoutes':"regex": "\\.css$""controllerName": "css";
