With achievements I assume you are talking about the "reward gallery" in CH1?
With Lain's installed you should get the images unlocked even if you don't follow that path.
Stick to Lain's is my advice.
Are you skipping Georgina's content though?
And I want the scene with her more then I want the achievement.
Because as much as I love Dee, Georgina is looking hella fine in that red dress....
Also, I found it weird that you are forced to delete the nude of Elena if you follow laine's mod.
I am unsure of what Georgina wearing her sexy dress has to do with not wanting to keep a nude of Elena...?
because I picked her casual clothing instead to see what changed, points with Dee are still the same but now I can save Elena's photo? Da faque?
Edit: Ha, figured it out, the "SleepOver" unlocks after "I don't love her" because the route for the Lain Mod make sure you see Georgina before having the sleep over with Elena. Derp. Neverminded my question.
