so i was in a private match (we where practicing trick jumps) and we discovered this.
you can shoot through it and if you where hiding behind there (not in it) you wouldn’t be seen. (we tested this)
edit (thought i might as well put this in too)
when i was playing dome i ran into the magic floating MG turret. it would move all over the place spending on when i moved. however i could only get on it in the designated area though. so mostly its just a nice little confusing bug XD
(mg is floating on/in the ramp)
