Male Sim breastfeeds infants/newborns regardless of gender settings
I have a male sim who I have enabled the "become pregnant" option for. However, the "produces milk" option is set to "no." Regardless, the option to breastfeed his babies still appears and he constantly does so autonomously.
I usually use some MC Pregnancy settings but this bug still appears with mods disabled. I also tried changing his gender settings to "gets others pregnant" but that didn't help either.
There is no need as I have found the solution. The babies I'm currently playing with happen to be from an alien abduction pregnancy, and the game has enabled the male sim to breastfeed for them only. This does not happen to other babies. It appears to be an intentional feature to override his gender settings in this specific case.
