[GTW] Doctor Career is completely borked

I haven't played the doctor career in a while, but the random townies having kids has nothing to do with pregnant sims, that used to be a system to make sure the patient was a mix between kids, teens young adults and elders.  You would only get a pregnant sim if it was an emergency and you need to be at the proper career level to get a pregnant sim.  The way it used to work is the pregnant sim would come you had to take them to the machine, the would give birth and the baby would disappear.  The reason why they changed it is so when a Doctor in the house goes into labor at the hospital she can't be a patient so she has to exit the hospital during her shift and if she comes back during her shift there is no doctor at the hospital to deliver the baby because the game still thinks she is at work.  Even though I never really experienced that bug it has happened to others.  Also there was another bug where if the pregnant sim worked at the hospital and was not a doctor but one of the other lower levels and went into labor at the hospital she would have to leave and come back and if during work hour the doctor would be there and the pregnancy would happen, but because it was during the sims work hours they came would think it was a pregnancy emergency for the npc doctor and when the mother came home the bady was never born and never returned home and the mother was stuck in labor.

Edit: I also have forgot to add that if the only doctor available for the doctor career was in the same household of the sim that is pregnant, when the sim is pregnant the Doctor would not show up because especially during work hours, because only one family member is allowed to be at hospital during work day, and even worse if the person was invited to come to your pregnancy.  Also pregnant sims that have the baby in the hospital without the proper pregnancy machine can't leave the hospital with the baby and it will never be added to the family.  That is the reason they made it a real pregnancy.
