Following on from the "Follow at a Distance" theory.
Have just tried following a Hafnium Convoy from a distance twice, 3.6km and 5.1km. Both times the wing jumped fully intact.
If there is method to guarantee or at least encourage the Conda escorts to get lost, there is more to it than so far recognised. Both times I had the T9 targeted, and my weapons stowed.
Did the extra wings leave sooner?
Did you close with the T9 when it started to jump?
I usually have weapons deployed though it would be strange if that made a difference.
I'll test with more convoys later.
