Maybe that question will be answered in the future. Also, in v1.0 there was a bug that did not show Madame du Barry's ending. In v1.0.2 it should work fine since it's not possible to miss her final event.
So, My whoopsie here, it seems. I just went straight for the ending last time around. On going back to my save point there, I dropped by the office this time. What the MC does there affects the prologues big time. So my advice to the other players is to spend a few days game time if you have to, and run through everything there first. The first one to drop by was Ramorray... Not saying a word, other than it seems when given the right stimuli, she CAN feel emotions. ;)
Also, there's another hiccup that I noticed. It was with Mia's epilogue. It ran twice, back-to-back, but different versions. The first indicated a rugrat, the second did not.
