I just noticed another bug. When my female sim gets pregnant and is showing, the husband can't interact with her unless she initiates it. Basically, it's not letting me click on her when he's the active sim. If I select her, she can interact with him. After she had the baby, he could interact with her again. But then she got pregnant again and the same thing happened again. It's not a huge deal, I guess, but it's preventing him from fulfilling wants to talk to or listen to her belly.
I have also had this experience.
I have this issue also and noticed that when the relationship between the husband and wife is just "okay", "friendly" or even "flirty" he can interact with her, but as soon as they hit the "very alluring" status, the bug rears its ugly head. No love for you !
