Ideas
I am also having issues with pregnancy in the game since the update.
The issue i'm having is the pregnancy isn't registering. So my sims can woohoo (which gets them pregnant because of mods) and they can take a pregnancy test because of a mod which then tells me they are pregnant but after that the pregnancy isn't there. My MCCC mod says theres no pregnancy and when i try to start a pregnancy with MCCC mod no sims come up to choose from. My sims also can't try for a baby rather than just woohoo and cannot take a pregnancy test from the actual game.
This happens with or without mods. I removed my mod folder when installing the update and have updated the mods that have been updated already.
This bug has made my game unplayable currently because of needing pregnancy for the household i'm in 😫 I forgot to back up my save too as i didn't realise what date it was and the update crashed my game and then started installing, i did manage to remove my mods folder in time though before the update thank goodness!
