v1.3 Glitching through wall Black Gold (minor issue)

Description:
There's a missing corner in a wall where is possible to glitch through. This may allow people to enter inside the compound from a side where it should be possible only with a rope.

Steps to Reproduce:
Load black gold insurgency; i didn't try other gamemodes, but since i presume it's a map design bug i assume it will be the same for all the black gold layouts/gamemode.
Go to D3 Kp3 (subkeypad 2). Look for the corner wall, you'll be able to see through. From the outside you also will be able to glitch through (may took 2-3 times to find the right angle).
I didn't manage to do the opposite (=glitch from the inside to the outside).
