It wasnt attempt of cheating, just wrong counting.
And dont worry about save game much, its pretty hard to corrupt it if you simply change some values. Look it up a bit, a lot of things can be changed very easily - like research priorities, production, nuclear production, tech trading, trade priorities... , a lot of things you will probably need to change regarding your alternate timeline.
You can practically create a completely new scenario just manipulating a save game. if you need any advice just ask.
EDIT - I forgot to ask, will you add oil to Libya ingame?
