Here's a weird one.
I'm attacking an enemy airport, in a city whose defenses have been eliminated. The airport still give the green sheen when targeting by air, but not the city center. There are both the enemy aerodrome commander and a air squadron commander, as well as one enemy plane, on the airport hex.
I am unable to attack the airport by air (no effect, planes do not loose move after clicking on the site). Same with land units (tank), they refuse to move onto target. The city center is occupied, as well as the other city hexes except the airport, and the city color does not change. Stalemate, no change next turn.
I move artillery into range, and lo and behold, shelling shows effect on the enemy airsquad leader. Continue until he is eliminated, and NOW, the tank is able to move in and the city changes hands.
Anyone seen anything like this?
