Alright, but ... I'm not sure this qualifies as a bug. If it's, say, turning around to face a Lasher while a larger ship is shooting it in the back, yeah, that's a problem.
If it's merely deciding to chase a frigate around because it's the nearest/most convenient target, that's something else. It's not as simple as "cruisers prefer larger targets than frigates" because then they'll get more easily flanked and this could lead to reduced survivability. In the player's hands, this behavior is resolved through orders, if necessary.
I can see how it'd be an issue in the tournament, but it's running up against a scenario that's explicitly not designed for - the AI functioning in an AI vs AI situation, with no ship under player control, and no orders being given.
