I played my sim as normal, got her pregnant, and everything was going well through the first and second trimesters, but after the second trimester moodlet disappeared, the third trimester moodlet didn’t show up. I waited 7 sim hours to see if it would fix itself with time, nope, still no third trimester moodlet.
