Impregnations, not births. Keep that timer on 7, pretty sure any other speed is prone to bugs.
I'm stuck with Kiriya, her 3rd achievement, gotten her 1st and 2nd ones already. Two people have listed two different ways to get it, and neither of them are working.
Have you found out the conditions yet? I have gotten zero prompts to follow her from there. Only possibility is that she needs to be at the gym first, but...
I've never seen her at the gym, ever, even with mass save scumming, to try and force her to appear. How do I get her to show?
I've saved up 48 mil. I want to get enough interest per week to afford Inari so she stays pregnant. It's taking a lot, I figured you need 125-150mil in the bank to be able to afford her once every 5-7 weeks.
