This relates to the behaviour of npc dents in some critical skirmish missions. Sometimes the mission is in large spread out sectors such as Initros H5 or Rhamus P 16. The queen flies off to mine a remote roid. The military npc dent follows but stops 5k from the queen, limit of radar range, still pointing at the queen which is well in visual range.

The player can still win the mission by running back and forth from the dent to the queen. However the dent just sitting there at 5k staring at rather than approaching the queen seems to me to be unrealistic so I think it is reasonable to flag it as a bug.

Thanks, we'll take a look.
