Merithra

I came to turn in "Call of the Dream" but noticed Merithra has 2 ooptions to play movies about the World Tree. I haven't seen either of them yet, even if they were previous in-game cinematics, so I decided to try. Clicking one one caused my WoW to crash by freezing up completely "(not responding)" until after a minute I manually closed the program. Opened WoW back up a couple minutes later, tried to click on the dialogue to watch the other movie... same crash happened.
I'm on a decent gaming computer that I bought new just a few months ago, it should be more than capable of handling whatever the game is supposed to be doing now.

Her gossip dialogue:

I swore that the tree would be kept hidden and safe in the Dream. Now all we have worked for is under threat by flame.

I will not fail. I must not fail.

If you do not fully understand what is at stake, I can show you. The Dream as we know it might change forever.

After this, players have the option to play the cinematic for what threatens the World Tree, or the cinematic showing how the tree was planted in the Dream.
