NPC Spawn Issue: Does Peffin Ambersnow despawn after a certain amount of time?

[Telin]

"After turn in she ran to the fire and we got jumped by the 3 in the room...killed them and paced the gaurds to take on Peffin solo. Paced them all and proceded to the back to get to her and just as we got to the back I saw:
Peffin Ambersnow says, 'The cowards seem to have fled friends, thank you for your protection.' Then she depopped."
