Merry Christmas backatcha gman9912. First, of all, no need to deep dive to find the "issue". It is most likely just a matter of understanding the Options available in the game. When you start the game, there is an "Options" menu, and under that, a "Gameplay Settings", where you made your choices for the Submarine School. Those settings also influence the Single Missions, War Patrols and Multiplayer choices. When you start a career, you end up in the on-shore Captain's Office in the home port. While in that office, left-click on the wooden radio console to your left in that view, and you will enter another Options menu, again with the Gameplay Settings choices. Those settings in the Options menu there apply only to that particular career. So if you are running (as an example) four careers concurrently, they can each have different Options set, and those could all be different from the main menu's Options settings. The Stock game, as well as most mods have a very similar set-up.
Now, this is the thread for the Beta pre-release version of the FotRSU mod. You would be better off using the v1.8 and patch of the latest release of the mod at
[REL] Fall of the Rising Sun Ultimate - v1.8 plus Patch, and to post any questions you have in that thread. It is "stickied" at this time to the SubSim menu, and will generally be found in the first few posts of the SH4 Mods Workshop section. Do be aware that there is also an original version of this mod, Fall of the Rising Sun (FOTRS) that was released by the AOTD_MadMax team years ago. Fall of the Rising Sun Ultimate (FotRSU) is an updated version of that, combining most of the work that AOTD_MadMax did, plus updated assets.
