Make sure your wanted speed to down the periscope is correctly set in the Hsie.ini file (main game folder, open with notepad)
As to Hsie options disappearing after activating all mods, it’s because you have other SH3.exe somewhere in a mod that overwrite the one you checked options...
Best is to have only one SH3.exe in main folder and delete the other (s).
Check all mods and see where is hidden the culprit...
Last, if you want to fully enjoy Ccom, you should not have the last 4 mods, all overwriting the environment folder and scene.dat … and probably messing up original Ccom distances & sensors interactions; but that’s only my opinion
Don’t forget there is a full map mod available somewhere, if you are using the nice Ahnenerbe_WS-GUI_1920x1080_for_CCoM_by Wurmonkel
