I don't know if it was a bug or if the RNG was just awful but when I was fighting the ravager it would not do its sex attack.
I had to fight that boss 5~6 times before it did it.
Are you using an old save? Maybe you need to fix the scenes in the memory room - there is a robot next to the red button that will fix the scenes.
No I started this playthrough from the beginning.
Also using the "Lewd" skill did not work at all for that boss.
