That's strange, try loading an older save and running through the content again. Make sure you're on v0.12.4
That's the issue, never cheat friendship unless you know exactly what you're doing.
For example, if you add a friendship point and that event was an anal sex scene, you never got an anal point. Which leads to you never being able to have anal sex with that character. And you should ALWAYS save before you cheat.
Don't forget about your auto saves.
