I think I've found something odd. I was exploring a new system and got a "new aliens encountered" message. When I looked closer, though, I noticed that I had *two* new contacts in my diplomacy tab. Both were "Sirius aliens," had the same race portrait, but different flags and a sequential race ID(#138 and #139). Looking at the system, I have two separate (huge) EM contacts coming from the same habitable planet in the system. One's 180k and the other's 280k, 280k also has an associated 50k thermal contact. 180k one may be too far for my surveyor to spot on passive.
I've got active sensors showing on four ships near the planet, which is odd because they're nowhere near me and the last NPR I encountered only went active when they detected me. Are they pinging each other? My survey ship's very far off, passive-only and has a very small thermal signature, so I don't think they've spotted me, and both have "unknown" relations with me.
Even odder, all the contacts belong to the #138 aliens. The #139s don't even have a system entry in the strategic Intel tab. Also, the planetary contacts and three of the ships are neutral grey, but the fourth ship is hostile red despite belonging to the same faction.
Is it possible that two NPR factions spawned on the same planet? I haven't heard of this happening before. If so, assuming they didn't start allied, do you think the "ships in owned space" and "shared colony" relations maluses will cause them to go to war with each other relatively quickly?
