My sim won't age up. I've tried using cheats, the birthday cake and just waiting. nothing has worked so far and her brother and sister who were the same age at the start of the game had no problems aging up. Please help

This was a solution I pulled off another forum.
"turn aging back on for a day and the cake will work again. Edit: 1 SIM day, not a real day lol"
