how long has it been since the update that let us actually see the programming be done on Renee and Loreli's trance triggers on a hypnosis run?
That came in patch 4.1.20, on December 17.
For those who don't know: on a hypnosis path where you are the hypnotist, you used to just install "a trance-trigger" in the various ladies, with no further explanation. After 4.1.20, you now install a specific trigger into each lady (there's a lot of permutations of what this could be). They resist at first, you push through, it's good fun red-meat MC.
I've put everything I've found out about it into my flow already, just check out the relevant section.
