I've just checked, and duds are enabled in the main menu as well as in the career. The only things I don't have enabled is contacts (because doing a lot of trigonometrics is not what people will watch

) and external view (I need that for recording playback).
Career has the same options.
My original loadout was about 50% (or even slightly more) duds, and all were running too deep.
But when I reloaded at Tulagi (once it opened), it sems I got some super good batch - all run perfect. Maybe it's when you reload during the mission?
