Q1: There's an NPR that I thought was annihilated.Not long ago, I got a Diplomacy update from them, advising me that they were now sharing gravitational survey data with me. Does this mean they still exist out there somewhere, or am I just talking to ghosts?
Q2: (related to above) Sometimes I receive a bunch of new system data showing up on my galactic map. I've never noticed an event update announcing this delivery. The deliveries seem to happen when I conquer the last population of some NPR. Is this something that happens when you conquer someone? Is it happening for some other reason? Am I overlooking an event update?
Q3: I get that scientists are more likely to gain research bonus if they're working in their specialty field than if they're not working at all. How does working in a field other than their specialty compare? Is that just like not working? Just like working in their specialty? Somewhere between?
Q4: Does the size & quantity of the mineral deposits found by the geological survey scanners correlate in any way to the size and quantity of the deposits that a geology team is likely to add? (Rephrased: I've got an extremely mineral-poor system with many bodies in it. It's in a strong strategic position and I'd very much like for it to be a mineral-rich system. Am I wasting my time if I go team-searching all the bodies therein?)
