Unfprofessional Dota 2?

So I went to go watch Unp Friday and for 50 mins it was stuck on Dota 2 Star Ladder's Twitch Stream instead of showing the Giantbomb stream. It finally fixed itself after I closed my browser and reopened it (closing tabs and hard refreshes didn't work). Not sure what happened, why it happened or how it happened but I figured I'd post it for you guys to try to figure out. If it helps, chat was working perfectly when Dota 2 was up and then was completely busted when the Giantbomb stream came up.

OS:

Windows 8.1 x64

Browser:

Firefox 28.0

Add Ons:

Ad Block (shouldn't be blocking anything since I'm a Premium member)

Last Pass

Manilla (for bills and shit)

EDIT: Also, it said 'Dev Test Chat' if that makes any sense. I'm guessing I probably just got sucked into whatever test page you guys had made earlier and my cache was shooting me back to that page over and over again until I closed the browser.

The Starladder streams were put on on Giant Bomb? Tell me next time.
