Something I just noticed about the Bianca buttslap scene is that either DPC is being
cheeky , or the tc variable change is bugged on rollback.
If you rollback after selecting "Grab her ass", sometimes it will correctly revert the tc value... but sometimes it will stay the same.
If you rollback after selecting "Gently place your hand on ass", then sometimes it will correctly revert the tc value... but sometimes it will instead give tc+1 again on the rollback!
And -
purely for science - if you were to repeatedly "grab her ass" or "place your hand" then rolling it back over and over again, the tc value will continue ticking upward.
So all you gentlemen who thought you were being sneaky on your vanilla Jill playthroughs by sneaking in a quick "Grab her ass" enjoying a little Bianca booty before settling on "Hover-hand", you probably still earned a couple tc points from that!
So far I haven't seen any other choices that have this issue, but I haven't checked them all.
