I'm not sure if I do understand what you're saying.

That's not a bug, that's supposed to be that way. As soon as the video ends, it vanishes.
I've got no issues with the story zone at all. It works as it supposed to do. As soon as the player walks into it, the video starts playing. As soon as the video ends, it's dissappears. While the video plays, you cannot interupt it at all. That's how the story zone works on my pc and that's what it's supposed to do.
