fixed internally Mission 12 minor issues

[Jasonmoofang]

Flew this twice and saw the following minor issues:

 1. really minor, but there're 2 blue shirts kinda in the way when taxiing to CAT I - since I'm parked right next to the cats I just did full right turn to flip around towards CAT I and found myself "running over" the 2 blue shirts

 2. for some reason, there is no way to kiss off Blade during recovery. He was stuck to my left wing, which made it pretty awkward during the overhead break since it felt like I was trying to ram into him. He stayed on my wing all the way to final approach before he broke off.

 3. there was no "mission complete" message. First time I flew I thought I might have messed up some triggers, but mission end screen showed full score. Same thing happened second time round.

Also found out there used to be some Tomcatting that got removed due to broken DCS AI. A shame for sure
