Why is my sims 3 neighbourhood only having girl babies?
It sounds like a mutation in cellular reproduction. If any of your sims work in a nuclear plant, anything nuclear for that matter, the radiation could be causing a mutation to the Y chromosome making it a X chromosome. In the long run, you could end up with an Amazonian society which is not good for reproduction. Your best bet is to limit there time around such materials or get rid of nuclear resources period but then some other sim country will threaten you with war and you won’t have the weaponry needed to scare them away. But then again, Amazonians are scary enough. LOL!
