In the Ritual Cutscene, I believe it is the second in the plot, when the leader of the ritual walks up to the device the animations for the ritual do not begin and the game sits endlessly, presumably waiting for the animation to finish. I tried beginning a new game to no effect and am currently re-installing the game to see if this fixes the issue. If anyone else is having this problem or knows a way to resolve it I would appreciate any advice available.
