Agreed, through reporting these problems it's actually to get fixed and technically a bug like this I've seen dozens of times on nost (Stranglethorn fever anyone?) where quest mobs or NPCs are bust or in spawned in via quest, they don't despawn and pile till server restart. Outside Stranglethron Fever, the water testing quest out in Tanaris is bugged too on nost where the beetles never despawn and result in this massive pile up that causes people to outright avoid this quest line
That's true. Quests like this are bugged on Nost as well.
