This in regards to the Sealed Chest and the items within.
Completed it last week and only turned in like 2-3 of the items. Went back this week and the NPCs are gone.
If I complete ICC again will they appear yet again? And if so does doing it on 10 or 25 matter.
We have faced trials and danger, threats to our world and our way of life. And yet, we persevere. We are the Horde. We will not let anything break our spirits!"
Edit: Herp derp, yeah. so long as you have the quest from the items and the item itself you can force them to respawn but I believe you have to kill LK again.
