Re: random genetics not letting me choose age of siblings / son/daughter
@avieerkul1 Hi! I just tested this in my game. I have a teen sim and using genetics, the game defaults to the same age (teen) but I do have the options to select Child or younger. The options to select Young Adult or older are greyed out because his parents are YA and "child" sims cannot be the same age or older than their parents.
If you mean that you don't have these options, please provide a screen grab like this. It will help to figure out what's happening in your game.
EDIT: To be sure, I just tried creating a "child" sim using the parents genetics and still had the options to set the age from infant through teen.
