This has happened twice now, so I wasn't hallucinating the first time.
As the Terrans, I have a planet tile on Earth with the "Planetfall" bonus. Considering we think we started here, that seems to break narrative causality or something. I love the bonus, but unless we are pushing the theory that aliens came down to ancient Egypt, it just doesn't make sense.
If needed or wanted, I have a save game to show you and could submit a ticket. Let me know.
