After you make alterations, you often have to empty the Save folder to clear the old data. That said though, the "small_patch" is the Terrible Tambor fix, which RSRDC also fixes, so no further work is needed on the mod for that. One thing to remember about the subs in the game is that they all have an "UpgradeClass=" setting in the SubName.upc file, which controls the upgrade "rating" of the various subs. Some are "zero", such as the S-Class. Some boats have the same number as other classes, such as the Tambor and Gar are the same, which is one reason you do not get a new command in the Gar. Same with Salmon & Sargo.
