What you had there was the "original" Fall of the Rising Sun (FOTRS) from the AOTD_MadMax team. That is what Fall of the Rising Sun Ultimate Edition (FotRSU) is based upon. In either case, there is a "dud" setting in Gameplay Settings on the Main Menu, Options choice, which governs the Single (Quick) Missions, Multi Player, Quick Patrol and Submarine School. For a career, you have to click on the radio console to the left when in the Captain's Office prior to getting on your boat, and change the setting in there for each career you have running.
