Anomalous Coffee Machine: 138/140 Sex Scenes (Workarounds)
Short answer
Suggested fix (unconfirmed): Trigger both variants of the Demon Maid ("Lust" and "Femdom"), the Cute Reaper Girl, and the Cow ("Lust" and "Milk") to unlock the remaining scenes.
The problem
I checked the entire gallery and confirmed that I was only missing the scene with the hell maid(386/755). I redo the scene, but the game still shows 138/140
Suggested fix (unconfirmed): Use forms with NSFW scenes instead of non-NSFW forms when drinking lust. Avoid combining "lust" or "sex" with non-H forms until the bug is patched.
