@EA_Davidre post #121: It was commented on a topic about this problem in Reddit that the distance was very specific. Fall outside of a certain range from Deathstalker, and the inspiration would either not trigger, or fail. With this is mind, and also being intent to capture video for you, I tested it. I stayed right in close on Deathstalker this fight, and sure enough, it triggered and I was able to complete it. So it is not a bug, and we can consider this bug complete, however, I think possibly the trigger conditions are too specific/sensitive, as I noticed on Reddit that I was not the only one experiencing the same problems. So it is more of a case of possibly not working as intended - but - if you stay in close all the time, it will trigger, and you will be able to complete it. Thanks for follow-up on my report!
