Anet,
I'm sure you're working hard on a hot fix right now. But, why does this happen in the first place? Why is a bug or set of bugs that effect so many events going undetected and pushed to the live server branch? How did QA miss this? It's discouraging to see as a player. It's especially frustrating because this bug effects lots of instanced end game content that has been plagued by unfixed bugs for months on end now. Why is this content getting shafted?
