I can't see alien ships in the tactical map.
I met an alien race several years ago (50 or so). Established communication and reached neutral status rather fast.
Until then, they come and go in my systems, without any reciprocal connections (1), so, every time step, I receive events of alien ships passing in my systems.
But, I can't see them in the map.
If I double click on an event, the map centres on the location. But nothing is there.
They are in the range of my planetary sensors. And Neutral is checked in the Contacts settings.
I remember I saw them, but maybe before reaching neutral status(?).
So, how can I have them appearing in the map?

Some strange things, anyway: I can't find their homeworld, and it seems I meet always the same ships.
In the Intelligence/Alien window, their ships classes and numbers don't change.
I have also two diplo ships around, but they don't gather info about this race.
In the game settings: no Precursors, no Invaders, no Star Swarm, no Rakhas, no Aether Raiders, no NPR generation of these menaces.
