Save crashes during loading

[yxoutcastxy]

I have been playing my save building my town for hours and about 10 minutes into playing it, my game crashes. Everything I go to load the save, the whole game crashes, not even in game error message. A windows message pops up and says sims 3 has stopped working and then it closes the whole game. I have tried running without custom content and cleaning saves, as well as clearing caches. any ideas on how to save my world
