With my group, we are trying to complete some remaining challenges. I am at 210/220 mission challenges and I still have the one where I must not “kill enemies” during the Nurgloth boss event, problem that does not work! We got bored, clearly for hours, trying to do recruit bosses for nothing, BECAUSE the challenge does not proceed. We tested everything, even the fact of not doing a “push” because when you push an enemy in the AOE of nurgloth, the enemy is considered to be killed by the player. So hours wasted for nothing. It’s very very frustrating, especially for players who are looking to finish all the challenges and who still have more than 1500 hours of play.
I hope that a moderator will see this message, that one will answer me and help me with that.
