Hagental Base clipping through map bug

I fell through the map inside the giant room with the wet floor and pallet racking's.
If you walk towards the left after entering from the front entrance that corner is where i clipped through the floor. 
If you're in squad deathmatch you're forced to spawn on a team member and the only way to get out from under the map is if you kill yourself and wait until your teammates kill themselves as well then respawn.
Here's a clip attached to this post after falling through the floor.
