Not sure if auto-investigating is the right term, but I'm talking about when an exploration ship finds some ruins (the three dots in a triangle symbol on the map). I started the game following the New Guys Newbie Guide, which turns off ALL automation, except this one setting. However, I just noticed that there were three systems with ruins which had not been auto-investigated. "Were", because right after I noticed, the third one was investigated, since the exploration ship was still in that system. Strangely, even though I have seven exploration ships, the only ruins on my map are in systems all explored by this same ship. So, any idea why the other two were not auto-investigated?
