the preg happens you lock in to one of ending! i did try to hide stuff as spoiler but it literally delete the text away soo better say it out now. my new game+ already finish. Earning 5000 points more than ever! i check the gallery and found that there still hidden stuff in there but i not really into this game anymore soo leave it at that.
i not sure when preg happens but at you can see in my first time to the game saves that they not preggy at all and game leaving me with 2 choices but new game+ game not giving me this choice at all. It might be i getting ton of favorability too fast and they getting corrupt too hard! or they get preg during corruption barrier level whatever it was at lv 2 and lv 1 will lock in ending i guess
