I don't know if anyone has seen this yet, or it could possibly just be me, but in the Train Tunnel(the one leading into NAFB) there's a little side set of stairs(inside) leading up to a room.
Every time I try to go up there, though, I fall through the floor and reappear at the end of the tunnel.
Anyone know how to fix this, and really, am I the only one with this problem?

Same issue. Just posted that actually....

What platform you running?

...
Xbox360S

I ran into this same issue on Xbox 360. I kept trying to make it into the room, one time I attempted to jump to the room and fell through the floor so it teleported me back to the entrance to the tunnel but it broke my characters leg. Also, when a ghoul fell into their he completely disappeared from the area.

Curious. I wonder if it's platform specific?

lol, I was just about to post a topic about this.

How does something like not having real floor in a zone EVER get past testing?

It's almost laughable.

So what is in that room? From what I see its just some scrap metal and some empty SS bottles. I also see door has dropped through halfway as well.
