Im playing FNV now and if i want to enter the tops casino a guy should say to me that i should give him al my weapons and the "camera" zooms in on him. But somehow my hud disapears and i cant do anything. Now comes the big problem. I quicked saved myself when i was stuck. So when i tried using the console with player.die/kill i kill myself but im stuck again. Can anyone plz help?

have you tried the console command: "coc goodsprings"?
or something like "player.moveto 00104c0f"
The former should send you to goodsprings the latter should send you to doc mitchells.
If neither works keep reading.

From tops casino on fallout 3 nv wiki (bugs section):
You may find that as you enter the casino, you cannot move and the greeter does not talk to you: the game is essentially frozen. Resolve this by typing enableplayercontrols in the console.

You could also try restoring the backup quicksave. Go to the saves folder and just remove the .bak portion from the quicksave file. Make sure to backup your saves first.

okay im gonna try it

ok thanks coc goodsprings and player.moveto didnt work because the camera still acts weird but enableplayercontrols did work. Sooo... Thank you!
