Praise the herald of andraste quest bug

I had same issue. Walking around kill dragonlings and trying to find this person. I went back to the fort with the rift inside and found and can talk to her but here it bugs again. It does not start a conversation with her.

The only way around this bug that I found is reloading from before receiving the quest and doing it again. This was so far back in my game though that I just got too frustrated and have stopped playing for now. Really wish someone could find a real solution to this.
