I've been running around Njikan scanning systems. Some systems i've never been too will still show the planets as unexplored and some don't. When dropping into a few of the systems i've never been too there are some planets that show a first discovered by and 1 or 2 planets that don't show any first discovered by. While surface mapping i've noticed that planets do not show a grid until a probe hits it. Then it shows the area covered by the probe. Some planets will show a grid before firing any probes and subsequently will not show the area covered by the probe. Has anyone else observed this?
