While navigating the bunker at GPS 0.25 0.62 in the Zulfiqar missile base (and other bunkers in that area), I noticed odd rays of light coming down from what seemed to be heaven. I thought it was a normal day and that I'd just been shot (again) and teleported back to the north... However, these rays of light seem to be some sort of grass glitch that move about similarly to how grass flattens as you move across it. See attached video.
