I don't know if this has been mentioned yet...I couldn't seem to figure out how to use the search function for this forum.
The AI for ships using auto-explore has some problems. First of all, a ship on auto-explore will go back and forth across an explored area, exploring a small part on one side, then a small part on the other, and so on. Also, if two or more ships are on auto-explore, they will tend to all go to the same area, and so the galaxy isn't explored twice as quickly for two ships, as it should be.
On a slightly different subject, it would nice if a ship on auto-survey would explore gray areas if it can't see any anomolies.
Thanks.
