I have done the quest "Chapter 4: The Bamboo Blossom" on 4 separate characters and every time I see the cutscene where Namsoyoo walks up my screen goes black after it whether I skip it or not. It just sits there until I end task to close the game and restart. When i get back into game my character has been teleported out of the instanced building and when I reenter the quest continues as normal. This is the only cutscene where this happens (so far) and it has happened to me consistently. However this has not happened to my wife. The cutscene itself runs fine.
