Strange Fighter Behaviour

[Vortex]

Playing Campaign 2 Last night - Defend the Abbidon Starbase.
Having waxed the Battleship and fighter escort at the warp point I trundled back to the base to deal with what was left of the two battleships and 4 destroyers that had gone past me.

Launching two fighters I neatly dispatched what was left of the battleships and then recalled the fighters.

Fighter#1 docked without problems, I had no damage at this point, but fighter#2 closed as if to dock and then started flying around in circles, looping as if it was going to dock , out to 5ls and then back again.

After I started moving again it fell in just astern and then docked correctly when I stopped.

Anyone else seen this behaviour?
