Forum:Homeless Sim Age Up Error

I was having a birthday party for my sim and I wanted to age up a sim with him so i had her blow out the candles and then she triggered a script error and was reset but she was still a child so i reset her with master controller and then she ceased to exist and error trap error messages kept appearing non-stop! I ended up just going to main menu to play another family and I don't know if this will continue to happen when I load up the save but if so I'm gonna need a little help.
