Frog-7 Campaign Mission 5: Unable to Complete due to AI Midair Collision; "SARAH 1 has been Lost in Action"

[SignorMagnifico]

Has anyone else encountered this issue with mission 5 in the Frog-7 campaign? (Strike on Damascus International)

Both times that I have tried to complete Mission 5 of this campaign, SARAH 1 crashes due to a midair collision with another one of the AI flights. In this last try, LIONCUB 3 crashed into both SARAH 1 and SARAH 2, causing this message to appear:

"SARAH 1 has been lost in action. Abort and change to waypoint 15 for RTB instructions." 

I'm wondering if it could be due to the AI not being able to handle being in such close formation or something else. Screenshot of the mission result and a .rar file with the track file attached.

I'm going to try turning off wake turbulence in my game settings and instructing the AI flights to go into a "trail" formation during the low altitude section to see if that helps.

Here is a video of the collision on YouTube. (Latest attempt done in DCS 2.9.19.13478.)

Side Note: For QOL update, I think the coastal waypoint should be set to a VIP point over the bridge, so Jester can get a nav fix.

Update: I managed to complete the mission and stop the AI collisions. What worked for me was changing the flightplans of SARAH and LIONCUB to instruct them to follow DOG flight at a distance of 2500m and 1000m, respectively. I also set SARAH to follow DOG flight at the same altitude, but LIONCUB follows at 200ft above DOG flight.

Turning off wake turbulence made no difference in the outcome. I also made the coastline and target waypoints VIP points.
