They found me, the proper NPR. They seem(!) outteched by us and they are very peaceful for now, hanging around us happily. After comms established, relations climbed to 32 then for trying I used the lightest request to make them leave Sol. They immediately agreed and went away. Relations got reset to 0. We meet in Proxima after some time and my diplo ship with %30 comm and diplo commander is growing beard on them. We are sitting on the Sol JP alltogether. Also I have Elint module spy ship there and it seems it doesn't do anything as well. It may be Elint module need to be close to their colony to get intel but I don't know.
