Webpack production build yields "Invalid Regex" error with Webpack2

[Nantris]

I have tried using transform-regexp-constructors and setting it to true and to false. No difference either way.

This doesn't occur in development. Any idea what if any change to webpack or .babelrc would be necessary to restore this functionality? It worked in the Webpack 1 setup.

Thanks for reading and for any advice!

It's a known issue it looks like: babel/babel#5564

It looks like the original reporter of the issue was also using the boilerplate from what I can tell: https://github.com/MatusSkerlik/Prezior
