Exploit? I crafted items at Mysterious Tent, Blacksmith and Sex Workshop. If you have enough items in storage it'll craft the item but not deduct anything used (Pink Cage and 3 types of Earrings).
At Mysterious Tent I crafted a Feminine part potion and some items that were in my inventory did correctly be used up but those from storage did not.
There's something not quite right with how the game recycles actors when hiring a new character at the guild or when they're born. The attached save file shows characters semi-randomly being generated with cow ears, regardless of which race they're supposed to be.
Also, hair styles that hide eyes cause the avatars to show up without eyes when wearing a helmet. Looks quite creepy.
