Just found a girl on the streets, recruited her, and she shows up dead in my brothel. It would make for a nice intro if this were a mystery novel starring a grizzled pimp-cum-PI, but this isn't, so it sucks.
[edit]
I can confirm that the game is ignoring the pregnancy timing settings in the config file. All pregnant girls seem to give birth the next week, regardless of what the config file is set to. It is also ignoring the growing time and cool down time (I haven't played long enough to see when the kids come of age, though I set it to 1 week, so I know it isn't working right. The cool down period is gone).
[edit 2]
Ok, this is really strange. I knocked up another girl, and the pregnancy timing stuff worked.
Also, the player's daughters are not getting the "Your Daughter" trait.
