Sex with Rivet?

[JWpilot]

Sex option for Rivet is greyed out with;
"You might want to know more about zaikas before having sex with one."
I have read all codex entries, clicked all conversations, bought a few items, and her affection is over 20, what flag am I missing?
Thank You in advance.

The removal of the Codex requirement wasn't properly implemented.

Filed a bug report.

Edit: Just got fixed for 0.9.115
