Under the texture spot on Tajikistan map's C flag

Hi there, played a bit yesterday and during one of the games on that Tajikistan map noticed people constantly popping out of a mountain cliffside on C flag even though no spawn beacon is there. 

Decided to see it for myself and found a spot where those guys were hiding. I don't know if you can shoot from under the textures but you can clearly plant proximity sensors and likely spawn beacons too. 

Here's a video with a clear explanation and I hope it gets fixed in full release: https://youtu.be/ce8nocbQWto
