I did today. You really don't notice but that place is HUGE. I spawned right at the top on a small ledge when I was soloing it. Connectivity bug, I was disconnected completely from my fireteam just as we were entering the labyrinth. I came back on my own and just spawned up there. Weirdly I wasn't in a dark zone either , so I could shoot down a gorgon and respawn freely. Anyway, right on top is this small area. It goes up quite steeply, and at the top is this small gate. You can't open it, of course. It's not meant to be there so the textures glitch out. I'm guessing it was meant to be a part of something but they cut it out for some reason. I have video if anyone is interested, but before I post it I need to know it's a common bug so I don't waste my time editing. Thanks
