I wish I had a way to post evidence of this but it seems the Dun Crim courtyard is somehow bugged for Volley GTAOE. I was inside the central keep defending against a large number of enemies who were in the courtyard. I had various attempts at GT at areas that were not under a roof where many enemies and catapults were. I never landed one arrow from multiple volleys. This has happened on more than one occasion. The number of volley arrows fired was well above any statistical miss rate. It almost seems like the entire courtyard is considered under a roof. Hopefully this can be looked at but something def seems off.
