Enhanced Lust Potion can't be crafted because it requires "Animal Cum", and the ingredient you get from animals is "Beast Cum". Reptile's Lure has the same problem, where the recipe needs "Swamp Mush", but the ingredient is "Swamp Mash" with an A.
And I don't suppose you could make it possible to plant Vine of Swamp in the Garden? Those things are tough to get ahold of, even by teasing the Swamp Creatures.
Absolutely fantastic game by the way, the Sub content is phenominal. The Dom content is sorely lacking twinks, but that's just a personal preference (though the Young Man from the Tavern seems cute). Gunnar is easily my favorite, but Troll, Barrel, and Hayden have some great scenes, and that Wererat/Young Man pic is the BEST.
Also, since I'm already commenting, "Sparing" in the Bandit camp should be "Sparring." Sparing means to show mercy, such as to 'spare someone's life.' Sparring means to fight non-seriously (spar), such as for practice or fun.
