This is caused by a change in the game Give Birth at Home code, not by the Pregnancy Controller. Note: There is a problem with male sims giving birth at home and then remaining with their only option being 'Go to Hospital'. If you're having problems with it, please report what specifically is going wrong in your game. It is NOT compatible with previous game patch versions. Version 5 should be fully compatible with patches 1.63, 1.66, and 1.67 according to my tests.
