I'm having two annoying behaviors. The first is, you can't make a pair takeoff with AI planes because each time they get to the runway, they instantly accelerate, even with a delay set on the last taxi waypoint AND on the takeoff waypoint. The other thing is weird formation flying. I created a mission with 9 Ju 88s taxi-taking off, then flying the vic formation. And each time they collide with each other while creating the formation (I mean no 3 too far forward, even before the no 1, so I eventually ended up with just 6-7 planes in formation). And they also like to drop their bombs early. And I don't mean several dozens of meters, I mean 2-20 km before they reach their target!
I don't know if it's my fault (bad mission making or something) or AI's, but I just can't make them listen to me
