When the Invader is a few metres away from the docking port (auto-docking), the station starts to turn away. The ship tries to follow it and re-align the docking port but in doing so only pushes the station round in circles at speeds of up to 50 m/s.

I do not know how long this might go on for as I backed the ship away to avoid damaging or destroying anything.

This seems to happen because the Invader's broad front interferes with the gravity ring and other parts of the trade hub station that stick out as far as the docking ports, which do not seem to protrude nearly as far from the main structure of the station as they do on other stations.

I know; why is a warship docking at a trade hub? Well, on a VIP mission you want to keep the VIP safe, eh?
