As soon as i add ?modules to the css-loader I get the following message after a CSS change:

[HMR] The following modules couldn't be hot updated: (Full reload needed)
This is usually because the modules which have changed (and their parents) do not know how to hot reload themselves. See http://webpack.github.io/docs/hot-module-replacement-with-webpack.html for more details.
[HMR]  - ./~/css-loader?modules!./ClientApp/css/site.css

I couldn't find anything that i'm missing to make that work. As far as I understand this should work.
I also looked for an option to pass reload=true to webpack-hot-middleware/client, but nothing seems to be exposed for that.
