Unfortunately the lewd scenes with the step-dad did NOT appear at all.
They were the first NSFW lewd scenes I achieved, but they were not shown.
I very thoroughly checked that I had the Maximum amount of Love, Lust etc. and NO Suspicions for the character.
I checked all the settings in the Preferences, applied the Scenes NOT appearing bug.
I have checked the downloaded files and the NSFW sex scene files are there in the game files, but for some reason they do NOT get activated and displayed in the game.
I also wish to point out all the text for the dialogue is shown, it is just the NSFW lewd sex scenes that are not being shown.
But unfortunately nothing helps.
Please fix this quickly, this bug is ruining a very enjoyable game.
