Moving Airport or Base (Golden Rainbow)

Hello to all, i noticed that when move the airport the aircraft remain in the old position, and the still behavior have the supply units with military base.

Any ideas why?

It has nothing with the airport, but with the units.

If you create new units for the same base or airport, they will assume the new coordinates.

And no, you don't want the old units updating to the new coordinates. Its impact is mainly aesthetic, at best as well.
