That happens to me sometimes, so I always save mine after something I do that I like. But, I have not found a way, I always have to just reboot my computer. Sorry :(.
You have to make adult sims (Make more than one). Then you use the ``boolprop testingcheatsenabled true`` You get the sim modder from pressing shift and clicking on your sim at the same time, it will be under the ``spawn`` menu. You click on it, go to set age, choose the sim you want, and choose teen.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
