[Azuremyst Isle] Quest: Totem of Vark / Shadow of the Forest multiple casts

[Ikarusit]

Originally reported chromiecraft/chromiecraft#7415

Current Behaviour

Quest: Totem of Vark [9542]
Creatures that are affected: Stillpine Ancestor Yor [17393]

"Shadow of the Forest" cast gets triggered immediately on quest pickup, blocking you from seeing Yor spawn. It should only be triggered once when you followed Yor out of the water.

Expected Blizzlike Behaviour

After accepting the quest Totem of Vark [9542], Stillpine Ancestor Yor [17393] spawns, talks, walks with you out of the water, talks his second Line and then "Shadow of the Forest" should get casted on the Player, morphing them and the quest continues.

Steps to reproduce the problem

1. Simply advance the questline "Learning the language" [9538] until the Quest with this issue: "Totem of Vark" [9542]
2. Accept it.

Extra Notes

Clients used for testing:
enUS + deDE

Weirdly enough, if you cancel the buff "Shadow of the Forest" recieved by accepting the quest, it plays out as it should, even recasting Shadow of the Forest at the right time.
I looked through the SmartAI entrys for both the Totem of Yor and Stillpine Ancestor Yor, couldn't find anything wrong with them though.
Maybe someone else knows why it gets cast 2 times, I'm missing something here 100%.
