I looked around and I think there was a bug in the script of the first date with Sasha, in the file JeniUpdate4 at row 2403
There's an = too much and the variable was never set, that's why at the time of the split it never showed Sasha's scene.
Sasha's scene also has some issues. I think there are still comments there and it shows both the subscene where she lets you cum and the one where she teases you and after it's over it goes back to Jeni's cuddling night (even if it's implied it's the morning after).
Anyway I got my reward for it, another scene with best girl Sasha lol.
Love your work
