In the Repair Auton screen at Corporate Auton Dealers multiple autons of the same configuration do not appear in the list of autons to be repaired.

Buy 2 of any auton.
Check the repair screen, no autons of this type/configuration will be visible.
Jettison one and check the screen again. The single auton appears.

Very confusing.
Seen in 1.9b3 and 1.9b3 git downloaded 2 April.
