Using pregnax causes a bug. You may acquire pregnax but adviced by the walkthrough to not use it. That's 17.5 version.Does anyone know if the Diana pregnancy bug was fix (if you use the pills) in 0.17.5 (Holiday version)? I was reading comments it seems as if people are having issues with this part of the game! Either players aren't getting thru enough events to trigger this or the game is still bugged. I have no interest in this part of the game, but I may save on separate slot when it comes to this event,and play it out just to see how this part of the story line plays out.
