Harmony throwing warnings when compiling

[snario]

All these logs from warnings are getting really annoying, and I can't find any reason why they would be happening. They only started recently (like 2 weeks) though -- no idea what is causing them.

webpack.config.js (loaders)

{
           test: /\.jsx?$/,
           loaders: ['react-hot', 'jsx-loader?harmony'],

           include: [
               // everything local
               path.resolve(__dirname, "js"),

               // troublemakers
               path.resolve(__dirname, "node_modules/react-progressbar/index.js"),
           ],

}
