I think I may have stumbled across a game-killer.
I've just returned to the Battle Tower after unlocking the 'You're going to die, Charlie' achievement, and it's completely devoid of staff. No Tom, Dick, or Harry, no one. Now it could just be the case that there's been a mass walkout due to low pay, and a strictly enforced 'no smoking' policy; but somehow, I doubt it!
Please tell me that this is fixable. I've tried a hard reset on the console, but the tower's still empty when I start the game.
