"Yes, unfortunately I can confirm that the 'not using submarines in the shipping box' tactic DOES NOT work. I was advised on a forum thread that not using subs would not anger the USA. Instead, this last turn, I not only anger the USA but I got the "Lusitania Event" which has shifted the US about 15% towards the Entente. This is another of those frustrating moments where my carefully laid plans have unravelled due to a bug in the game. How can I torpedo the Lusitania when my subs have been sitting in Wilhelmshaven harbor and have never been anywhere near the shipping box?? Now I calculate the US will enter the war about a year earlier than I had planned..."
Is this still happening? Can the US be angered by surface raider attacks?
Has this issue been patched or was the idea that no U-boots equals no negative effect wrong?
If so, I have also been a victim my own bad advice; I'm currently playing a pbem game as the CP, and my strategy in the West is based around delaying the US entry by not invading Belgium and keeping U-boots from attacking Atlantic shipping.
