Liberation Peak Glitch Spot

I found a Glitch Spot on Liberation peak above C in the rocks there is a spot where the rock is unfinished and you can get into the rock and place a spawn beacon which cant be killed. when you spawn in the rock you cant be shot and can see out of it to spot for free points. I also found you can't shoot out of it but if you inch forward until you are just far enough out of it you can shoot out of it and not be killed.
