You can change gender %s whenever you want; then you can make the purchase the next time slave market updates. If your sex factor is high enough, you can get her to lay with you instead.
Thanks, I'll try that. But it's still a bug in design, isn't it? The fact that your settings can lock you out of completing a quest and you have to edit world options.
Heard this discussed elsewhere & encountered it myself ----best suggestion I have is increase (for future versions) % of ELVES. (they're popular w lots of pple anyway)
