The hole in textures outside the shattered square map

Bob_Mayson

I experienced this issure only twice of 8 games on the map the shattered square. Once when the exit gates where behind main building in close proximity of the corner of the map and other ( is on video) when the exit gates were behing the killer shack. It looks like straight zone without ground textures outside the map near exit gates. Is it common bug?
