I am leveling an alt on Threads of Fate and am doing the Maldraxxus campaign (Aid the Necrolords). The quest description says you can progress by doing world quests, bonus objectives, killing rare creatures, and running Maldraxxus dungeons. However, I have killed 3 or 4 rare spawns solo and the progress bar has not changed at all. Should the rare spawns around Maldraxxus be giving credit towards this quest, or is it very specific rare spawns? I think this may be a bug
