I currently have a diplomacy ship orbiting what appears to be a mining base of an alien civ, with whom I have established communication. I know where their homeworld is, and they've told me to leave, and they have ships flying around, so I know that we're in communication and that they're not a spoiler. However, I cannot for the life of me seem to establish diplomatic communication. Or maybe I'm just not getting any feedback that I am talking to them and improving their opinion of me? Normally an alien civ also shows up in my space with their diplomat, and I get regular messages saying how my opinion of them has gone up, but that's not happening here.
Do you think they're slowing starting to think better of me due to my diplomat ship, but I just don't get any visibility into that, or am I doing something wrong?
