I don't know if you can do this, but I'm requesting a fix for the "Roundheels" hair. There's some weirdness on the back of the teen, child, and elder hairs - particularly on the child and teen hairs. It looks like the hair originally came with a hair tie, and with your version, the hair tie is transparent. It sometimes looks like the hair tie is picking up the texture of the clothing the sim is wearing, or like a chunk of the hair is missing. Is there any way you could fix this.
