I've actually deleted the game since I wasn't getting any replies, but I don't think I had that quest. If you could describe it, I might be able to remember but I'm not sure.
It starts when you almost got caught by Cecillia (the catgirl) while 'playing' with Rika (the housewife). The thing is, the quest tells you to go to bed and think it over. But when you do, instead of scene you got interface crashed and you can't do anything but go to title and re-load the game.
