Subs lacking crew

[pythos]

I am trying to do some detection range tests with the more advanced german boats. I created a mission with one elite black swan, and one german boat.

Only problem is, the subs have no crew. I am wondering how I can add crew to a single mission boat.

did you remember to select player controlled?

Yea. Also, only the type XVIII is lacking crew, all others have crew.
