I have just under 30 hours, man I'd hate to throw it away. So I go thru a door (a 'loading' door) and my followers Veronica and REX and I appear somewhat overlapping and I'm kinda floating. I can fire and goto PIP and look around but can't walk and there is no HUD. I fast traveled to many other spots, always the same. Even blasted Veronica away from me but still stuck. I can't talk to either follower. Her and rex ran off to kill something, but my feet are still frozen. Funny thing too- if I duck, Veronica ducks. Seems to me Veronica and I got fused a bit in the transporter.

Also fall through the scenery often, stuck in terrain often. Game freeze often... I think the best game ever made but NV really needs help.

I'm a fool and didn't savegame- just have autosave. Anybody have ideas how to salvage my game? Can I maybe alter savegame file- spread us out and/or get HUD and movement back?

Are you on PC?

Yes I'm on PC. Win 7 Pro 64. Fast rig. No major issues til this bug.

Try open up the console and type in "tcl" (without quotations), this allows you to move through objects. Or if that fails you could try the "movetoqt" command which teleports you to your current quest objective. As for bringing your HUD back I dunno, perhaps it will come back if you move through loading zones.

If your HUD isn't showing, try the command enableplayercontrols. That has worked for some people on this forum when their HUD has disappeared. And as Jolbo said, tcl if you're stuck inside your followers should work. Movetoqt might not work if the HUD fails to reappear after fast travelling.
Good luck!
