Please Help me, if you know what have happend to Juan Yang... Or Juan Hong?!?

I've got four sims, Ayane Oyraxí, Hotaru Okazaki, fd. Juan Yang and her son Shinichi Yang. I've invitedthe sons father, Liang Yat Sen from China, but i got bored and wrote 'tesingcheatsenabled true' and made him into a teen. Before the father should have arrived, i went to China to meet him instead. Then everything just turned... CRAZY! It where standing that Juan Yang had a broken heart, after seeing her love die. When i looked at who her son knew, i saw a child girl, named Yue Hong. I got chocked when it where standing 'half sister'. When i hold the mouse on Juan, i got really chocked! It didn't stand Juan Yang, It said Juan HONG! I Haven't changed her aftername, nothing! I looked at the family three of Juan, i saw that it was her daughter, not a girl of Liang Yat Sen from China! I klicked on the girl pickture... And i saw Juans face... And an old mans face! It said he's name was Chen Hong! I don't know whats happening! But the family three says he's alive!

HELP ME!

This isn't the life story i wanted of the great karate master Juan 'Hong'. I wanted her to have a boyfriend in China, and call her JUAN YANG :'(. It's day 1/14. I will write if something more happens... What if Ayane or Hotaru... Or maybe Shinichi gets an dead partner all of a sudden?!? HELP!
