[80] [The Raven Stones] I can't click on the stones

Well, this quest is part of a questline that allows the druid to summon the Raven Lord, however I'm on the Icecrown server and I can't do this quest. When I use the [Scenario Sparrowhawk Whistle] the bird appears, it finds the stone but it's not clickable, and I don't understand why some druids have managed to do this quest, but I know it's a bug.

i just did this quest 4 days ago, you just have to fly to a location called "Skettis" in Terokkar forest , and use the whistle .
if you can't click the stones it may mean that you are in a raid group .
being in a raid group bugs almost all the world quests.
