I'm not sure this is actually a bug, or if it's already known, but: It's possible to make the bot moan at the very beginning of a frick session even if she not able to speak yet. After a few moments (or maybe after you stop that first interaction?) she stops reacting and behaves as expected. I discovered it by rubbing her clit as soon as the session started.
Otherwise, great mod! A big improvement to an already great game!
