In a game I'm playing now as the Yor, there's a minor race (the Andians) who seem to have gotten it in their head that it's a good idea to build a few influence starbases right next to my capital. Okay, fine. Only one problem. I've never met them, and they are nowhere near me. I've demolished two influence bases already, and there's a train of three or four more constructors going right to the same area that I've also wiped out. I can't figure out what the point of this is at all, though they are devoting some serious resources to do it. It's not like their going to convert my planets by doing this... Wherever their home planet is, it's outside my range, so I don't even know where the train of constructors is coming from...
Such behavior would make sense if they were doing it around their homeworld... Maybe they think my homeworld *is* their homeworld or something?
