I promise to upload soon the instructions for the HUD to this blog.
If you need to update more than one baby, you need 1 disc per baby and do it one at a time. Don´t try to update more than one at the same time. This time anyone can make the update and the family list won´t be lost anymore on each update.
After making the update, rez your baby again for him to load the personality.
Don´t try to update unborn babies or they will be lost or update from other version that 2.06. If you do you can loose the baby´s personality or need a medic kit to heal him.
