I'm currently trying to do the mission G.I. Blues for the King so I can get into the strip, but The King disappears whenever I am about to report Orris' false protection to the King. I have tried resetting my character, turn on and off the xbox,and leave the room and fast travel. Will there be a patch or something to fix this? What do I do to fix this?

Did you look everywhere? I forget when, but The King moves upstairs at some point, to the third floor (his room). Check up there.

thank you!
