Well there was a Mk. III planet near me with a Mk. V Beam Frigate fabricator, so I launched an attack against the Mk. III Ion Cannon they had there, killed it, and got the heck out to rebuild the half of my fleet I lost and make repairs. However, the taunt did not come for a little while later, so maybe I just had a ship stuck there with no engines that didn't die for a while? It was funny none the less.
