I found another small bug. when you have lizard or lamia scales, not skin, but an additional part of the scales, then later when using TF items that change the face or they can trigger on the front part an unlimited number of times without changing anything.
that is, you spend TF items and don't get any other TF items because they are spent on the nose. even if you use carrots, for example, for a rabbit TF, and this item, after it changes other parts of the body, will start changing only the nose.
and that's how all TF items that can change the nose work. but not the beak of a griffin or a harpy, and not the nose of a dragon.
