Since the most recent patch, sometimes it is impossible to start the first event in Discord Tower - The Mindblight. We've been farming this for months already on Mangler, so we certainly know how it works. Typically, the event starts simply by walking up to The Mindblight and aggroing it. On some occasions now, the boss simply will not aggro no matter what you do, and the event cannot be started. We had the entire raid standing right on top of him trying to attack, taunt, AE nuke, anything we could do to aggro him. It just simply doesn't start. This bug is inconsistent, as dropping the DZ and trying again had it working normally. This behavior has been confirmed by at least two other guilds on Mangler since the most recent patch. We had never seen it before this month. Thanks in advance for looking into it.
Can confirm for Mindblight. We had it happen twice since 64 bit patch. We had a DZ part way done when we started mid dungeon and had the Syracana event do the same thing. Strangely the black and red daemons just before the fight went as normal when the Syracana event was frozen.
Nothing on discord tower fights, but we had the Mindshear avatar not become active again after one of his FD's. The event reset itself after a bit since we could not aggro him.
Had this happen last Tuesday on Mangler in Tower as well. Pulled 3 DZ's in total and he wouldn't activate in any before we moved on to other zones.
