when you go to close it the box will pop up asking if you want to save your changes. if not you either already saved your changes or you never made any.
click on wht you want to change then click the value in the window to the right and at the bottom a small box opens showing that value, make your changes there.
if you did that then maybe you didnt setup your files to install correctly when you made the mod folder.if your not sure then make a huge change just to see a change in the game to know your doing things right.
maybe the change you made was just too small to notice.
look at my torpedo test missions, they might work for v1.4, if not use mission editor to setup every merchant or warship or both and make them all docked. then run tests to compare "x" number of torps to sink each ship with setting "y"
