Today I went to a watch a Youtube vid and for some reason just about every channel I'm subbed to showed up in the feed, usually the only ones that show up in the feed are the ones that I watch frequently but pretty much all of them popped up. As you can imagine it took forever to upload, the only thing i can think of that caused this to happen is me clearing my cookies and browser data as I had to do that to watch something on HBOGo since it acts funny sometimes on Chrome. But every other time I've done it the feed glitch never happened.

Has this ever happened to any of you and do you know how to fix it?
