I believe that there may be some unseen force that is refusing to let me complete this challenge. It would seem that I have another problem, and Google isn't giving me any advice on how to fix it...if it can be fixed at all.
So, here is the deal: I am currently starting my 3rd generation. My 2nd heir moved into his wife's house, and they quickly got pregnant and had a baby. However, the the baby was brought home...he refused to age. It has been at least 4 days and he has not aged a single day. I tried to reset him to see if that was the problem, but it was not. I went into the options to see if aging was was somehow turned off, but it was not. My other sims are aging fine, but the baby refused to age.
In addition to this I copied the file to see if I could age him up with a cake to fix his aging problem, but it did not. He aged up with the cake but he did not age another day after that. What do I do. Do I have to start over?
