i found this train station next to rauls shack in the mojave. you need 100 lock pick to get in but halfway through the tunnel you encounter a door up some stairs but evertime ive tried to walk there i fal through the ground and it puts me to the start of the tunnel. im getting really frustrated because i have no idea whats hidden there so i hope that bethesda are coming out with and update to fix this bug

This is a known issue. At least on the boards. We'll see what the patch has to offer.

ok good to know. is there any clarification when the patch will be realesed?

Most are guessing it is a week out. However they have yet to release a list of what is addressed in the patch.

on December 7th, Bethesda submitted finalized version of the patch. It should be live on consoles and PC soon if it's not already up. I haven't had the chance to play the last two days, but I imagine it can't be too long of a wait now.
