Maybe I'm just a bit too used in how I did things in the previous version.
So after they disobey I use first words "if you don't behave, things will get worse".
But can't keep that up so first slapped her. She fought back losing me a day.
Next I tried to use torture, she acted up and I lost another day.
3rd time in dang row after I now tried public humiliation instead... she went and started fighting me AGAIN.
Having her fight back 3 times in a row (with me losing a day in between due to fatigue from the fight) just made me go screw it and I closed down the game.
Back in 2.01 when I first tried the game out this was never an issue and I've got like 1000 days recorded, so not particilarly new, even if a bit rusty.
Is there something I'm missing in how to deal with this?
First of all, they won't obey everything equally. If you ask her to do a blowjob from day one, punishments are not likely to work (unless they happen to give the slave enough fear, which would increase obedience, which you can check in the aura).
There's also the stats of the slave to take into account. If she has low endurance, you'll not be able to do much training everyday. If she has high pride or temperament, she is likely to be a bitch. And the slaver stats are important too.
Also, you only said the punishment category. Not the tier of punishment. If the slave doesn't feel guilty enough, you won't be able to give punishments that will be effective after many repetitions.
Try to also get obeyed and get the slave merit... Gifts and stuff are important to raise the mood on short term, which makes it easier to raise obedience on long term.
Finally, the main difference with 2.1 is what order gets obeyed first. In 2.1, fitness was likely to get obeyed from the get go. In 2.2, depending on the slave, she might hate doing cardio and prefer to learn music instead... Or she might plot to kill you and therefore is more likely to accept being taught how to fight. Or she might refuse absolutely anything until you work on her mind long-term (explain her position works three times, that's already a start... Then there are a lot of other things to raise obedience, clothes and accessories to help specifically with that, etc. It's part of the pleasure of the game to solve the puzzle on your own)
But... I suspect there's a bug; at least on my save, my slave feels guilty for some actions instead of merit. I'm waiting for Imperator_Augustus to confirm and fix.
