Hmm, did you use commands or a save editor to edit the points? For instance the highest Love points for mom you could currently get are 40 and you got 88... ^^ (Using cheats in this game could break your save...)
The sophia trip only triggers if following conditions are met:
Code:
aunt2love == 15 and aunt2corr < 5 and kristel_sex3 == False and pro12 == False and pro14 == False and pro15 == False
Your Aunt2 love and corruption points are wrong and you can't trigger this scene (you could try setting them back, but I suggest you to start a new game or use saves from someone who didn't use cheats, because it could be that next version anything else could be broken...)
This message is shown during the Sophia and during the Aunt2 Quest, where exactly are you stuck? Normally they should both trigger if you go to sleep (and you didn't use cheats to raise love/corruption points)
