Was doing a four man fire storm citadel run, when Vanaduke was about to enter his third stage in his body form and was about to summon the two slag guards, I think one of my team member used a shiver, didn't really see what happened but Vana just just stopped and standing there in invulnerable form.
Hope you guys can fix issues with Vanaduke once and for all so the trip before it doesn't go waste.
Really enjoy fighting the bosses you guys made :D, looking forward to new T3 bosses ;).
