Not sure if it’s there intentionally or not but yeah, there’s a huge untextured wall that blocks the left stairwell (left when facing elevators). It goes from the second floor all the way to the stop, making the stairs unusable. I noclipped through it to see if it was maybe blocking a missing part of the stairs but no, the stairs are perfect except for the big wall, so I figured it wasn’t intentional.

Also, I just popped back into the game while writing this, to see if I could figure out where the wall was coming from and boy, did I ever. There’s a massive untextured wall behind the wall with the elevators, and it’s part of the big wall that’s cutting into the stairwell.
