#15: Arachnae have scales, and correspondingly have the 'enhanced scales' option in the laboratory. From what I recall, spiders aren't known for armor. I assume this wasn't intended.
#16: During the boffing mini-game, the ladies sometimes will not accept the "take lead" command, despite being all-green. This happens for both humanoids and monstergals. No reason or response is given for why the command won't take.
#17: On occasion, the tooltip of a servant would be present during the boffing mini-game. It doesn't go away, obscuring the text log of the session. The latest time this happened, I noticed that Maple participated in the last boffing session - and it was her tooltip during the latest.
