Grunt task fails with no explanation

[vernak2539]

Running karma with grunt using jasmine, and phantomjs seems to crash a few tests before the end. This recently started happening, not sure why.

adding --verbose to the end of the grunt command didn't seem to log anything useful. Can add later if need be. Not exactly able to update module versions at the moment

Windows 10
node v4.2.3
npm 2.14.4
