Lucky 38

First, everyone disappeared from the top level of the casino, although the HUD says there's a plenty of NPCs. And yes, I know that the big Mr. House's monitor is an NPC too, so are the securitrons. They are not present in the room, although the HUD says they are. Besides I can't see them, I can't bump into them and talk to them.

Second, Victor just won't let me out of the penthouse. I'm pressing the use key while looking at him and... nothing happens!

I don't have any mods which affect the appearance of the game levels or NPCs. How can I fix this?

I was pressing the "Random page" button, and it took me to Lucky 38, I read through it, but then I came across this, I tried to track it down, but I can't find where F76's Wastelanders mentions the Lucky 38. Can anyone tell me where it's mentioned, like a note or terminal entry, or something?
