twitch: Unable to extract authenticity token

[TheRyuu]

For a few days I've been unable to authenticate with twitch in order to watch subscriber only vods. I know this worked on the 20150704 build so I tried that one as well and got the same error just to make sure it wasn't anything that's changed in youtube-dl.
