At the end of "A Long Night of Solace" if you had points turned on and go to vehicle kills, it looks like little Sabres above the kill count for Seraphs even though it is labelled as Seraphs. Might be an old bug but I didn't see anything discussing it and wanted to see if it was the same for anyone else.
It’s likely due to the angle at which the tiny icon portrays the Seraphs. From a distance, the two ships look very vaguely similar which might be why it looks like a Sabre on the results screen.
