As for the order of the screenshots, you are correct; the numbers are the date and time I made them, so the order is chronological. I forgot to mention that.

The air sorties in Preferences are set to the default XXX.

I rebooted my machine several times in between, and still get the same result.

In your example, why is the the purchase screen expected to come back after you bought the 8 Apaches?

I was able to repeat it more than twenty times since yesterday, only the number of attack helos needed to be bought to trigger it varies. It doesn't happen always, but in 80-90% of my attempts.
