[Bug] not working quests dustwallow marsh

The quest [The Brood of Onyxia] part you need to destory 5 eggs aint working cant attack or target the eggs.

the quest [Spirits of Stonemaul Hold] you cant seem to target the Remains.

The quest [The Grimtotem Weapon] is very hard to do because the buff the totem gives is only for one second and you need to time your kill very good to be able to complete it.
