Inquiring minds would like to know if you've actually taken a photo of Janice at the pool instead of adding the photo to your inventory with the cheat mod. If it's the latter you'd have to remove the photo with the cheat mod and take an actual photo at the pool, if it's the first you'd still have to remove the photo with the cheat mod and hope you can still take a photo of her at the pool.I can't "show the "naughty" picture to Billy" at school. Anyone else stuck there?
(Yes, I cheated, but I didn't go over the points in the WT. Mainly just gave myself energy and items.)
If it's still screwed up then you have to grab a save file for the section (v0.4 needs v0.4 save) of the walkthrough you are on and continue the game with that.
The cheat mod should only be used for add/removing relationship points and for the time skipping function, adding item should only be done for consumable items like condoms and sunscreen. Never should it be used to add game advancing items like the screwdriver for example as that will screw up the game triggers.
Anyway I am out as I can't think of anymore option to solve your issue. Good luck.
