Escape Alone Objective bugged

[Roomba]

Cyborg Tau-49 (played by Protowizard) was a traitor!
They purchased 3 items with their telecrystals!
They purchased:  Funny-looking Revolver,  Clown Car,  Chameleon Bomb
Objective #1: Cause significant damage to Security. Failed
Objective #2: Hijack the emergency shuttle by escaping alone. Success
The traitor has failed!

Jimmy Jam (played by EristheSlackWyrm) was a late-joining traitor!
They purchased 2 items with their telecrystals!
They purchased:  Fake Cleaner Grenades, Cyalume Saber
Objective #1: Cause significant damage to Mechanic's Lab. Failed
Objective #2: Hijack the emergency shuttle by escaping alone. Success

Two traitors succeeding in escaping alone in the same round seems...contradictory, to say the least. Especially when one of them was a borg.

Also neither of them were alone on the shuttle, there was a full crowd when it departed and when it arrived at Centcomm.
