Unlocker will fuck things up, so do that if you wanna come here in a few days wondering why your game melted itself. That thing should be removed. Better option is to use the phone debug, it'll fuck up your game too, but at least it's less shady and you actually have to click through 2 warnings, so you know it's all your fault if things crap up
And Jenny's preg might require her 1st preg to activate the scene. You may need to restart the game/route if it doesn't work (on top of all the above about the unlocking through phone/3rd party)
