My baby was born with a psychite addiction even though the mother did not take any psychite drugs. She was, however, taking penoxycline to prevent malaria etc. Could be a bug in which penoxycline is recognized as a psychite drug. Also, been reading some of the earlier posts. Maybe you could allow an option for users to set the age scale. Some want immersion and have the scale be like real life and some want a truncated scale. Some may be happy with the turning into a competent child at 3 years old scale.
