Didn't notice that. I got killed, on easy.
Anyway I did notice a few things while I was playing.
1) Five ships in Beta Wing. Even FRED doesn't like this one. Although it's possible to have wings of up to 6 ships that doesn't mean you should. If you need more than four bombers to make the mission playable what you could do is this. (I'm making it so that there are 6 bombers in Beta wing rather than 5 cause I'd rather make the mission a little easier).
Delete Beta 5. Open the wings Editor for Beta and set the threshold to 2 and the waves to 2. This means that once 2 ships are killed another 2 bombers will jump in.
Add an event using percentage-ships-destroyed to check when 2 ships in Beta wing have been destroyed (i.e percentage-destroyer > 33%). When this happens send a message from Command saying that they've managed find an extra two bombers to help and are sending them along.
Doing that will allow you to remove that ugly extra ship from beta wing without screwing up any of the events that refer to beta wing.
2) You might want to add some more vasudans to Gamma wing. Having only 1 ship present in the loadout screen looks odd.
3) Beta Wing has no primaries by default. What are they supposed to use? Harsh language?
Seriously though, this is cause the Artemis can't actually carry the Akheton SDG they've been assigned.
Sleepy. Will check again tomorrow
