Claw of Jormag Bug
I can confirm this. Was there from the start of the crystal pre-events. Just after the crystal closest to Earthshake Waypoint was destroyed the other remaining crystals ‘died’. The final crystal appeared, lost 90% of it’s life in seconds, then vanished and the Claw part of the event started.
The Claw started in ‘stunned’ mode, rather than raising the ice wall. The nextcycle of wall-stunned dragon went as normal, but the second time the dragon dropped 90+% of it’s health and started the final phase of the battle. It landed, regenerated health back to ~50% but died out of nowhere within 5 minutes. During this entire time the corrupted elementals and icebrood creatures were also going from full health to near death after a single hit, even the veterans and champions.
Also unusual, the Ice Worms that usually occupy that area repopulated almost immediately after the dragon was slain, before people even finished looting the event chest. There was also not an event completion notice after the Claw died. It did count towards daily event completion however.
For what it’s worth, the event also seemed to have started about an hour and a half before it should have based on the last event before it.
