Ok a few things I have noticed in game... (new pilot file)
The UE ships randomly attack ships (mainly scouthships) in the southern areas (Ariane)
UE destroyers appear as Leviathins(31d), have a similar turning speed, and have no weapons at all.
it might be plug-in problems, but all I have installed is Coldfusion(all), the shipyard, and Extreme Huge Explosion plug.
