When on the quest Strength to Weakness in Korthia, everything from Scholar’s Den to Seeker’s Quorum is phased out. I can understand Seeker’s Quorum because of the last part of the daily, but the rest seems like a mistake.
Still bugging out today. Events appear from a distance and mobs inside of them can be targeted but they vanish at about 100 yards. It appears to happen if you’ve charged the lightning pod, but not finished the part where you ride the mount and shoot the mobs.
