Just man up and resist the temptation to reload except for starting new sessions.
I find that a really poor attitude.
The simple fact is for many people an Ironman mode adds enjoyment and a different way to experience the game. We are not talking about reloading everytime anything bad happens but what serious and down right unlucky problems occur. E.g. spending many many years with sliders and such to westernise only for the comet event to hit as your young King came to age with the correct stats. Then when getting +3 stability again for your King to die before a stupid pointless war you aren't even actively participating in finishes. Resisting a reload there is difficult and an annoying distraction. A 10 second reload is tempting while closing down the program and restarting it quite simply is not.
Taking it out of our hands with a simple one save, no reloading and save when quit takes that out of our hands. That is all it needs, any other addition is just fleshing it out. But those 3 extremely simple features would add enjoyment for many of us.
