Control - Broken Moon - Possible to get beneath the map.

I was playing Control on the Broken Moon map, when I saw some textures missing on the map outside, I walked into it to see if it was a graphics glitch or what it is was, and to my surprise I fell through the ground and I was out of bounds, attached is the video from my gameplay. If the video doesn't work its posted here: https://youtu.be/3pLtJnIuba4
