Ok, I can see that. Don't have a save - I decided to try an iron man career (save only in port); it worked for three patrols.
But I see what you mean about having the damage AI "catch up" with player actions, because that first depth charging pretty much knocked out everything.
I'll have to keep practicing with the flood damage control; from your post it sounds like the damage repair team works faster/more efficiently if the boat is at GQ than if you merely activate the damage control team....
Thanks!
