I'm getting error below when running mocha in watch mode. As you can see, the file it tries to find is not even js file. Apparently the file link which breaks the mocha is somehow broken. It shouldn't break the mocha though. Without --watch, mocha runs just fine. i'm running mocha version 3.1.2 with following command from package.json:
"test-rc": "mocha 'frontend/*/.spec.js' --watch"

The error is following:
