So.... I seem to be missing something.
I've played through the game multiple times now (because it's bloody amazing), and the first playthrough I did.... ending spoilers below....
.... I didn't do everything necessary to finish Rebecca's path, and lost it for the end. However - went back and talked to the priest, finished that step, and got the good ending, with all seven girls pregnant at the ending scene on the bus.
I have not been able to accomplish this ending since, even with ensuring I was on the path for all seven girls. Got the bus ending scene, but none of them were pregnant.
My question is - does anyone have a list of the actual trigger points for each pregnancy? I know Carla's is in the hot springs, but that's the only one that the downloadable walkthrough clearly defines. I'm obviously missing one, or something's glitching out, one of the two.
