I'm having an absolute blast with this game, but I did find an odd visual bug. I'm running a Lustspell Witch playthrough, with an entire dungeon full of naked futanari. (Don't judge - I love my nudist hybrids, and they love their queen.)
However, each time I interact with one of the naked characters in the character inspection... their balls get bigger. It's cumulative and seemingly limitless. After several interactions, their balls are hanging below the floor in a grotesque, stretched parody of a tanuki's pouch.
It doesn't affect gameplay in the slightest, and reloading the game corrects it instantly; furthermore, it doesn't seem to occur with clothed characters. 100% reproducible - screenshots on request.
