Steps to reproduce the issue:
Play “Into the Nest”-mission on legend with some folks who are interested in doing the challenge “More where they came from”. This challenge requires Skarrik Spinemanglr to kill 40 of his own ratmen. However, he will stop and do nothing after a while. He stops functioning in the far left corner (when looking from the entrance, where you drop down). His fellow rats will continue to spawn, but he himself remains idle. Usually we had someone who could go invisible in the fight.
How consistently the issue occurs for you:
4 times already. It’s not that care about the challenge so the boss gets deleted in less then 10 seconds usually; sometimes even in less than 3. But everytime I managed to find a team of aspiring people who wanted to do the challenge, he (Spinemanglr) just stopped working.
Screenshots and/or video evidence:
Sadly, none. However I can take a screenshot where he fails to function (if I gte the chance). Usually he gets deleted instantly.
Off-topic:
Compare that to “Convocation of Decay” end-event. Lol.
