Error when trying to adopt baby

[Eleonora]

I'm getting a weird error when trying to let my sims adopt a baby. Judging from the text that popped up, my game is trying to create a new baby by using two townies as 'parents'. Thing is, my neigbourhood only has one townie left, the others have all been married in.
Am I reading the log right and is my single townie really the problem? Creating another one for the sake of adoption is no big deal, but it seems retarded the game can't just generate a baby from scratch.

Yup, that's pretty much the problem. Don't adopt babies when there aren't any in the pool.
