Have noyiced this as well. Once i had 4 contact's, one roughly north,2 to the south and one east. All were reporting about 25Km at 15knots.
No mather which way I travelled or for how long . whenever I stopped to take a reading they woud be the same distance out.
If I changed course they would appeare to chande course to mathe me, therfore always staying the same distance away.
Read a post previously that some had the same problem, they used the camera to find the ships. and confirmed that they appeared to mirror his actions. Must be a Major Bug.
