The text "First you need to complete April's quest" appears in any girl I try to take a photo with (Office girls and Gym girls both give the same text). But when i select the Buttjob option on April's dialogue it says that I should bring some new photos from the gym.
This is bad, most likely the only way to activate the scenes normally at the moment is to replay the save to get the camera from April again.
Maybe in the next versions I will make some function that will allow players to receive items that for some reason did not appear, or were moved in the game code.
