Okay, sorry if that wasn't clear enough here is what has happened.
Gabriella was a toddler, she then reached her birthday. Diana threw a party for her. After she aged up she had a makeover, trait selected and ate some cake. I then saved and exited. Yesterday when I opened the game up Gabriella was now halfway through the Childhood life stage with half of the bar filled, it says she has 4 days left till becoming a teenager when it should be 7. It is the same day and only a few hours after she grey up hence the Birthday moodlet. School starts in 2 Days for her and that means she only has 2 days to get to an A. The problem is that the game has made Gabriella older than she should be, it has reduced her time as a child which is really annoying. I am worried it will mess up me being allowed to choose her traits.
