And how it's going? It's still not fixed, as I reported before you need to firstly complete "Zero Xuks Given" (yes it sometimes bugging but it's better to try) then "Chains of Iron" will appear. I recorded video, as you don't really believe meZero Xuks Given was removed due to a Blizzard-end bug causing the NPC to fail spawning.
I'll need to send a tester out to it to see what other quests are affected, but on video guides of these quests - it seems "Chains of Iron" was there before doing "Zero Xuks Given."
