Guild Wars 2

Hi, I was playing the first personal quest with a sylvari, awaeking, and when a npc teleported me to te troll’s cave instance I exited the game.
Now I can’t get in the intance again because the npc don’t teleports me and I can’t countinue the personal story.
¿Is there any way to restar the mission?
I’ve already try to exit a reenter, teleport , chage character…
Tahnks.

I have similar problem, in the map I need to talk with “mender aviala” but in story journal is already done. I cannot start “awakening” istance.

Yes, same to me. If I’m out of the area the green mak of the mission appears on mender aviala but when I enter to the area where she is the mark dissapears.
