[REPRODUCIBLE] AI Civ is using my airport!

[whynes]

Version 1.0.0.26

Single player.

SETUP: I am Pericles. St Petersburg, to the south, is facing 3
full strength mobile artillery (armies, ***) units, with two stealth
bombers, in range, to the east. St Petersburg is weak, and will
fall this turn.

HOW TO REPRODUCE:

1 - turn 237) Pound St Petersburg with all available
ranged units, and then take the city with the two nearby modern
armor units.

Notice: the east-most mobile artillery unit is sitting right on top
of St Petersburg airport, which shows 0/4 air units present.

Now, click through the remainder of the turn, making any
decisions you please, just to get to the next turn.

2 - turn 238) On the next turn, move the mobile artillery unit off of the
airport (which is now in my territory). It still shows 0/4
air units.

3 - turn 238) Save the game, exit the program, reload the program,
on single-player, click "resume."

Now you will notice that the airport, now in my territory,
is occupied by a Russian jet fighter!!

The airport still shows 0/4 units, but there is clearly an
enemy fighter graphic there.

4 - turn 238) Again, click through the rest of the turn,
making any decisions, just to get to the next turn.

5 - turn 239, accept Russia's offer for peace. The
Russian fighter artifact is still there. The airport does
function as my airport; i.e., I can move into the hex,
and re-base my own air units there, but the Russian
fighter is still the graphic that appears there.

I hate to point this out, but an unoccupied airport allows landing of aircraft. More to the point, why didn't you simply kill that airplane?

Thanks for pointing that out. I actually didn't know that. But that isn't the case here.
Or, it wouldn't seem to be the case, anyway. I have a ground unit occupying the
airport. I have my own bombers relocated to that airport. Yet the Russian fighter
still shows there.

Furthermore, when I was at war with Russia (step 3 of my original post), the
airport showed as empty. Simply saving and restoring the game is when the
Russian fighter appeared (airport still showed 0/4 capacity used, though).

Turn 238 began (step 2) with my mobile artillery unit sitting on top of the airport
tile. Russia hadn't had a turn to move a fighter there yet (not until step 5)!

As far as I can tell, there is no actual Russian air unit there. It's just a graphical
artifact. Whatever it is, there is no way I can figure out to attack it or kill it.

Oh yeah, definitely a bug. If a foreign military plane is able to land on your airport, it should at least be killable, as it's on the ground.

Are you sure the Russian fighter isn't just Patrolling there... fighters can patrol far away from their base.
