I did a quick search to see if someone else has posted this. I didn't get any hits on it.

I'm using the 1.05 beta.
You can get double the number of squardons you are supposed to. Select maximum fighters then right click to unselect the fighters while they are building then select maximum bombers. You will now get 2 fighter squads and 2 bomber squads for each hangar or curiser carrier. Or double the number of squadrons a capital ship is supposed to get. This is an easily replicatable bug.
