After you play a Seduction card, what's supposed to happen is this: It goes to a passage called "Continue Seduction" that processes a bunch of game logic and determines if an orgasm has been triggered.
If an orgasm is triggered, the choices change to "Cum inside" (or "Knot" if you're playing as a canine species) and "Cum outside"; otherwise the sole option displayed is "Continue".
It sounds like what happened was you got to that page after playing a card and it was just blank? I don't know why that would happen. I'm looking at the code right now and it seems fine.
I went to try and recreate the issue, and the same thing happens when in Negotiation. I select a card, it shows some stats and then there's never an option to continue. (I never got caught before so I did not know.) Here's the screen cap from the current situation. Scrolling does nothing, and I also used Tab to highlight any links. Nothing.
