I assume its from an ablity point on the mesh of the ship.
Yes, exactly. How you orientate that point has no effect. The BuffInstantactionType: of the Vasari ship is "CreateFrigateAtTarget", where as the Tech's is just "CreateFrigate". It may be the difference I'm seeing. I have tried giving the Vasari the "CreateFrigate" entry, however this gives a "No String" error.
