I came across a weird bug today when playing on the DayZ Village community server. The moon was just rising above the horizon and was shown as an ugly square instead of its regular shape. I have never seen this happen before, so it might be difficult to reproduce. I'm enclosing a video showing how it looked. Shortly after saving the video the moon went back to normal, maybe due to coming a bit higher up in the sky? Enclosing a screenshot of that too below.
