Child bonus broken?

[Iggy]

Running the 1.6.5 patch on the Atari version.

Specifically, I'm married to Feanora and she's given birth to Serj (+20% DEF). I'm sure he'll grow up to be a fine son, but at the moment I'm not seeing any bonus modifier at all. I can account for each of the 15 points of my current defense score with the items that I have equipped (or the shrines that I've visited). I would expect my actual defense to be 18?

I don't see the defense bonus on my creatures either. Each of them have a straight +15 on their DEF score, so it doesn't appear to be a passthrough bonus either. Or am I just missing something?
