Hangar destruction problem

[Kyubnyan]

So I just killed 2 hangars in the same city and got these results:

You ordered a naval attack upon the nation of Schwarzenfels led by Halife Karolus XII Rex. The attack was an immense triumph. Your forces lost 0 ships, while Halife Karolus XII Rex's defenders lost 0 ships. You used 3 tons of munitions and 2 tons of gasoline executing the attack. The attack destroyed 1.25 infrastructure in the city of Akkon and destroyed 1 improvement, an air force base plus 18 aircraft inside.

and the aircraft were never killed so this dude currently has max air. https://politicsandwar.com/nation/id=84929

Destroyed a hangar and 18 planes, but they still have max despite not having logged on in 15 hours.
