I just started having the issue when Trying to get an Alien baby through Abduction. I had to use cheats or mods to get a male sim pregnant if I rolled for the percent which is normally 25%. Something happened after a patch. Unmodded and clear cache when I tested this. No Luck with pregnancy. Male sim I used the science career since that helped with getting abducted and never got pregnant. I tried many times and no luck. I think it is a bug.
Since it seems like a fair few people are having this issue, if you play an unmodded game it would be helpful to attach/paste in your lastException.txt files, because they do indicate that this is a bug, and not an issue with the game balance or just random bad luck. You can find the lastException.txt files in your game files (the ones generally under documents/sims 4, not the install files). They will be dated according to when the bug occurred, so you may want to reproduce the bug to make sure you get an accurate one.
I've had a male Sim abducted probably 20 times and no pregnancy. Working on first gen extended Not So Berry challenge and need alien baby.
@nhostthegobody and everyone else, the update was only for console players. If there's a major update, the game disables my mods. It didn't happen this time. What I think is most frustrating is that people pay money for an expansion pack and that it doesn't work properly. EA should be quicker to fix all the bugs (I've found a bug ages ago about chicken eggs that get spoiled, it's a crucial feature of the expansion pack and they never fixed it). People should be warned if there's a bug before they pay for an expansion pack.
It's rather annoying that you have to use mods if you want to play the game without getting troubled by all the existing and known bugs.
