Up and Away Quest Bug

Just had the exact same bug. I was waiting for the prayer in the "Up and Away" Quest to start and suddenly Varric and Iron Bull start talking and break the scene. No way to fix it.

Good to know it isn't just me.

I thought this had happened to me, but I reloaded and did it again amd noticed something. Given Inquisition's level up system, perhaps you are like me, who misunderstood and expected to get a skill point. When I did it, I got +1 Strength. An attribute point. Hopefully you missed it like I did and it isn't a bug. Just a suggestion. 

It´s not the quest reward. She just doesn´t start praying and the quest is still unresolved.

I had the same issue, solved it by loading an earlier save, then loading the save after she starts praying again. I got the point and the message that the quest was resolved as I walked away.
