Today i have tried the mission 3 times, but was unable to get the package in formation together.
They just fly directly to their orbit positions after takeoff, messing up the trigger at WP2.
I'm running Open Beta (2.5.5.34108 ).
Here is a track of my last attempt, showing this behaviour: https://drive.google.com/open?id=1c4A8NIpqlhSEq-NBfpNPx_f1Tj_FpLEC
Is something broken in the AI?
