MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: [2016.09.07-08.00.56:388][ 0]LogInit:Display: LogBlueprint:Error: Compiler Error Blendspace Player ‘(None)’ references an unknown blend space from Source: /Game/ShipEvacuationContent/HumanModels/PassengerCharacter/TeenMalePassengerAnimBP.
You are referencing an invalid/non existing blendspace and then the cook errors out. This may happen because there are issues with the animations for your PassengerCharacter, on each animation cook it errors out. Maybe check the animations again and reimport them.
Also, if not already done, run a “Fix up redirectors” on the folder (with right-mouse-click)
Hope that helps!
