@lambssims One may be infertile or transgendered. I am having that issue now. I got the magic pack and made my Sim marry one of the sage sims. My sim is fully fertile (you can select that in create-a-sim). The sage had a wosh to 'try for baby' but when I try all I have is woohoo. Their friendship and romance bars are both maxed out. So, it's a Magic Realm glitch (a few of those are noted) or perhaps the sage sim was created to not be able to reproduce. The blonde sage's features are also somewhat feminine to me so I thought they might be trans!
