I think I have identified the bug for the drinking mini-game.
As for the Holo scene, what was the last thing you were doing before it asked you to return to the Arcade? It may be related to the activity in the holo scene.
As for the holo I was doing followed footsteps story line got to cantina tried the drinking game (we know how that ended) which led me to try the holo training. I got to the three targets and it said continue our arcade.
