I've beaten Sinspawn Gui (the boss on the Mi'ihen site) twice now. Both times, the battle ended, it started a cutscene, but then froze, in a manner of speaking. The music is still going, Gui's tentacles are still bouncing up and down, but nothing's happening. It's been about ten minutes now. I know there's supposed to be a huge cutscene and then another battle, so how do I fix this?
