Btw, for the text bug hunting, the one which makes all the text bold or italic, dunno if that was pointed out, but drinking Bimbo Liqueur is a trigger for the bug, as is asking Joy about yourself, and at the very least the bargain route in Kate's 2nd encounter.
Also, something I'd like to see in the mod would be Tengu, both TF and NPCs; probably a derivative of the harpy (though about as related to them as the kitsune are to the fox-morphs), with a high focus on speed, some on wisdom and just a bit on strength; they'd probably have a few thing to encourage a dervish playstyle, and especially get a bonus if one was to use any kind of sword. Perhaps that could be expanded into a separate swordmaster line of perks? The NPCs could perhaps be included in a Mountain Peak area, or in the lightning/thunder area that was talked about a while ago.
Another TF that would be cool, tho that one is very controversial, is an angel TF. I know that's been talked about a lot before, and it doesn't match Mareth's theme, but well, I'd still like to see one. Plus... I thought about, if demons abandon their soul to achieve the final conversion, maybe angels would be the opposite, fusing their body with their soul or forgoing their body to achieve true angelhood; maybe they could be especially powerful and pure Soul Cultivator, maybe combining with white magic. Being made of Soulstuff could make them either immune to corruption or hard to corrupt; this could however also make demons especially dangerous to them, cause, well, a person-sized snack of soulstuff... yummy. Or if they can get corrupted, they might become (living?) statues of Lethicite. Finally, in regard to sexuality... Well, I have the picture of the faceless, genderless angel in mind, which would leave anal as the only natural penetration possible... Plus some or all of them would prolly see sex the same way Dr. Lash does in TiTS. Of course, well, that makes them harder to include in CoC with how much it is focused on sex...
