Detailed problem:
Unable to complete the quest Shadows Uncast (Immortal Flames). The NPC is stuck on the green exclamation mark. I get a confirmation that i have completed the quest however i'm not awarded any XP or the next mission and the NPC (his name is Swift, in the Hall of Flames), remains as it was with a green mark. I have abandoned the mission already and tried to run it again. Same problem occurs. Hopefully this can be fixed asap. As Its blocking me in my progession to level my Grand Company.
