Heroic Anduin Phasing Bug

[Namisan-garona]

Same thing happened to us on Normal Wednesday night. They probably broke it when they made it so Anduin auto-transitions at 10% health. I added the log in my thread:

Anduin 10% health Remorseless Winter bug

When fighting Anduin in Sepulcher of the First Ones, during the second intermission, if Anduin reaches 10% health and transitions to phase 3, the Force of Will damage reduction will expire and players will take full damage from a few ticks of Remorseless Winter. https://www.warcraftlogs.com/reports/RkGwTXDtAc3CP2HL/#fight=21&type=deaths&death=5
