Warning: It looks like you're using a minified copy of the development build of React.

After updating all packages (#42), I noticed this big red warning in the JS console, when viewing the production version (made with npm run build):

Warning: It looks like you're using a minified copy of the development build of React. When deploying React apps to production, make sure to use the production build which skips development warnings and is faster. See https://fb.me/react-minification for more details.

Not sure if this was an issue before #42 or not.

I alse have the same question. Did you ever resolve it?

Seems like this was a red herring caused by some kind of bad state... not sure what the issue was, but it's give away for me.
