Apparently there's some sort of bug or glitch happening with a large amount of YouTube users. If you make any changes to one of your videos such as changing the description or tags, the video will get placed "Under Review" and out of monetization. I've read through some of the posts on the Google forums and read that YouTube IS aware of the problem and they're working to fix everything. Because of this though I will likely wait to upload the God of War parody until this glitch is resolved. If I do happen to finish before things are back to normal I'll also finish up the Breaking Bad parody in the meantime.
