Awesome, thanks for getting back to me so soon, and answering my question! There is one thing though that I should clarify:
"And lastly, I believe adult characters are automatically turned on when you disable childlike characters. "
Yes, that is indeed what the options screen says happens, and what should be happening, but what I'm saying in my report is that disabling childlike characters while adult characters are still disabled doesn't actually re-enable adult characters automatically. If you do the actions outlined in my report, then despite both childlike characters being disabled and adult characters being enabled, the game will act as if the opposite was true, which is especially noticeable during character creation if you try to create an adult player character or slave. I hope that clears up what exactly the issue I'm trying to point out is.
