Hi all,
I observed this on 0.99a : took a mission from a Korolov shipping station. I undocked, saw the freighter undock and ... that stupid animal kept turning on itself without ever getting on route to anywhere...
I tried to dock at the station, it would always tell me to get back to that poor ship alone in the dark... I finally had no way but to blow up the freighter and as it was my first Korolov mission I got banned from escorting anything !!!
Maybe it's already fixed in 0.99c...
