Planes on a strike mission enter a holding pattern with a flightplan

[Ekaton]

So, basically one of my strike packages entered a holding pattern en route to its destination. This happened to me previously with a different package in a different scenario. I've set all flightplans to maintain a separation of one or two minutes between take offs and they seem to be following their plans except for this one (Hitman 44). Last time it happened to me in a scenario, planes just ran out of fuel and crashed.

I am playing on the Steam version.

EDIT: Nevermind, several flightplans entered loops by now.

I tried a fresh scenario I created in the editor. Out of 8 packages, 7 were fine, although AI chose an incorrect altitude for ordnance required for one. One package circled endlessly until it ran out of fuel, despite having a valid target and flightplan.

EDIT: Replaying the same scenario, at least one package enters the holding pattern, and not the same one as before.
