I am having the same exact problem at this very second! That's how I found your question. And I tried playing another family that I have and it doesn't freeze on that one, only on the one that I really want to play!
So I guess maybe I will have to delete that one and make a new one :( but if you find any answers that work please email me!
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.
