So this is a planet owned by me that had an evac building (while owned by me), was invaded (destroying the evac building) then recaptured. Hovering the pop icon also shows a predicted -2 change in pop as if the evac building was still there.
That is karma for throwing innocent civilians into the void under guise of evacuation in an attempt at scorched earth tactics, weighting on your consciousness
From my end, I see that building as "Destroyed" with me as owner (debug dump still shows you as empire that built it). Surely destroyed when I took it over and I saw it happen. Maybe your client thinks it is "previously visible" with you as owner, not having witnessed the act of desctruction? I think you did not have visibility on the planet once you lost it at the time
