I'm currently arriving at Sagittarius A from an extended sightseeing trip over the months and scan every thing of importance in each system (dozens upon dozens of earth-likes, ammonia worlds, neutron stars, black holes and water worlds discovered). I've heard that a lot of commanders lost data during the 1.4 update. Now that the Engineers release date has been announced, I don't think I'll be able to make it back even if I make a straight line back to Quince without the scanning because I'm currently in a middle of a few projects. I'm not even going to worry about the updated AI and interdictions anymore, but I am fairly concerned about the update somehow messing with the data I've collected as that is far beyond my control.
