I found an alien colony on a planet I had colonized for a couple of years when I built a Deep Space Tracking Station on the planet. I have been attempting to communicate with them for several years now, but to no avail, no notifications on progress or even notifications that they refuse to communicate. I am beginning to suspect they don't know I exist. I have turned on active sensors to make my presence known and I'm not at all being subtle, but nothing seems to be happening.
I have attached my DB if it helps. The aliens in question are in the Barnard's Star system and I am playing on a 1. 9. 3 install.
Thanks in advance.
