Hi gazpode
Yes, I am referring to the game play settings in SH3Commander.
If you want to be able to have realistic career length then you tick the box.
If you want to have crew transfers then you tick the box.
You can have one or both in your game.
Here is the important bit.
You only click in the box or boxes when you start a patrol/mission when you are docked.
When you finish your gaming session and exited, open SH3Commander again and click in the box or boxes again so the tick/s are removed and then exit SH3Commander.
If you are going to do a test patrol (Eprobungstelle) do not click on the box or boxes until you do a real mission after the test one.
If you always want the same captain and the same crew then never tick either of the boxes.
