I made my sim go to China and get a NPC from there to be her boyfriend. Later, I invited him over and tried to get them engaged- no matter how many high-level romantic interactions they did, ''Propose Marriage'' did not appear. The next day I made her go back to China and try proposing marriage there and it worked, but she had to go home before they could actually get married so I invited him over again. In the box that appeared asking me who I want to invite, it listed his relationship to my Sim as engaged but when he actually came, they were strangers. I got them up to romantic interests but ''Ask to go steady'' didn't appear, so I tried a random sim from Sunset Valley and again, their relationship wouldn't go higher than romantic interest. Also, her family tree wouldn't open- neither could her brother's, his wife's or their children's. Can this be fixed somehow?
