There are a number of hot fixes and a couple notable bugs we wanted to bring to your attention. Ideally all these will be fixed soon, according to our standards and not according to Blizzard's definition of soon.
First is the Malygos bug where Circle of Healing and Wild Growth were not function when a player was in a Vortex. Ghostcrawler has posted that this will be getting fixed in the next couple of days. I wouldn't be surprised if this is fixed tonight.
Daelo, the lead encounter designer, also came out today and said the following with regard to what they're looking at: "We're checking into the various issues noted here, including why his cone breath hits targets behind his centerpoint, issues with malygos deciding to attack in phase 2, and trying to make the defense bubble's protection work even if you enter the bubble in between the time a missile is launched and when it lands."
