HMR not working with Vue (always doing full reloads)

Hi guys,

I set up a project using electron-webpack using Vue.

HMR is enabled but I always get this error:

> **Cannot apply update. Need to do a full reload!**
> module.exports @ log.js:26

Happens with any other CSS file, too.

I tried to add "if (module.hot) module.hot.accept()" in my renderer/index.js, and then HMR doesn't do a full reload, but changes in my templates during runtime are not adopted anyway.

Any ideas?
