AI wingmen sometimes collide when changing formation

[SnappyComebacks]

When changing formation, occasionally the wing men will collide with each other.  My most recent instance attached is when the flight hadn't completely formed up.  (Number 4 was lagging behind, 2 & 3 were in position).  I changed formation to "Spread Four" and wingman 2 + 3 turned into each other and collided.

Track and Tacview attached.  (~10 minutes long, incident happens at the end.)  The mission was the second mission of the F-15C campaign that comes with Flaming Cliffs 3.  I am on the current Open Beta.

Hopefully the General Flight Model is not far off.
