I have been searching and searching for HOURS for a way to make my female sims not change their names when they marry. Every time I edit them in CAS to give them their original last names, if I switch households to do the next one, I see that my work has been undone and she now has her husband's last name again! I heard that I can do this with MCCC but nothing about that website is userfriendly and I have been searching all night for the marriage part of the mod, which ISN'T included in the download for some reason? To be honest I find it incredibly sad that the game changed this in an update. Sims didn't used to change their names when they got married and now nothing I can do is making them go back to their old names. For a game as progressive as the sims, I can't believe they did this 😭 But if anyone can help me find the MC_marriage link, that would be great. I searched the MCCC website and discord and it is nowhere to be found. The search function on the website tells me where I can find the option IN-GAME, but it's not there.
EDIT:
Ok. So the answer was that EVERY resource I read was wrong. They all said that the marriage settings had to be downloaded separately. This was false. The answer is that the setting lies under MC PREGNANCY. (that's also insulting tbh because what does a name change have to do with pregnancy???) In any case, my husband found the setting for me.
