At the end of one my escorts the transports ended up idling near the destination station instead of docking. After a while they disapperead one after the other and the mission completed. I tried to ram them and they seemed to disappear in the order of my ramming attempts .. but it could have been a coincidence.

Another odd thing about that mission was that one of the bots raced way ahead of the group. I think it even jumped directly at the starting station. The whole covnoy seemed to go faster than normal.
