Didn't have a single highlight touched by this and it really doesn't affect me in the least. I just got my partnership on Twitch a little while ago and I'm a speed runner; I just had the foresight to stick to game audio and upload stuff to youtube anyway (the Twitch VODs are shit for a number of reasons).
It doesn't affect livestreams and hopefully they will go back on the 2 hour thing and reduce the 30 minute penalty for muting to something like 5. Even better if they flag games that get hit for their own soundtracks as immune to those specific matches (like a cover in a GTA game).
Ironically or not, the day this happened I had the largest gain in my follower count ever. "shrugs"
