What happened to the Slovakian Air Force?

[VictorCharlie]

In my ongoing Beta 5 Grand Campaign, the Slovakian Air Force has disappeared!
On turn 31 there were six squadrons in the 2 airbases.

Come turn 32 five squadrons vanished!
Nothing mentioned in the Event Log.
No Soviet units were adjacent to the airbases.
No Soviet air attacks on the air fields.

So where did they go?

[VictorCharlie]

Turn 32 all gone!

[Helpless]

They must be withdrawing.

[VictorCharlie]

Ah i see.
There was nothing in the event log though about the withdraw.
