@DinowCookie Aw thank you, that's so sweet, glad you liked it :)
Also, about the MCCC thing, I too have found I've had a lot more multiples with that mod. From what I understand it makes the percentage even based on whatever you set your maximum allowed births to (so, if you set triplets as the maximum then it's 33% for each one, single, twins or triplets, if you set quads as the maximum it's 25% etc etc). The sets of twins I shared all happened within the first 4 pregnancies of my legacy (and the 4th, a single, was only that way because there was only one household slot left). I've opted to set my own number and gender of babies with a random number generator now so that I don't have so many multiples.
edit: about the identical twins thing, I do vaguely remember seeing that setting, will have to check that and see what percentage it's set to. Maybe I've just been unlucky with having no identicals.
