Unfortunately with twist, unless you're following the walkthrough step by step and to the letter it's very easy to miss triggers or bypass a trigger, never to be able to get in the future and especially if you using a cheat mod.Just to be sure i redid all anal scenes with Danielle, the trainings with all size, anal at night and day + the shooting. The other half is done as i would not have the option to speak with Michelle about it in the afternoon, but still no option at night when i should ask her again. I think i am F-ed. There is no way solving this, or at least i don't know what am I missing.
Best advice I can give, is for you take a look at my saves, via the link in my signature, and pick the one the fits where you are in the game.
