Bug with armor

lore vest ------------------------------------------------------------------------------- a blue and yellow striped vest can be referred to as 'blue yellow striped vest'. It is worth 1520 copper, and is of the 30th level of power. It is armor worn on the body. It is made of leather and weighs 7 pounds 7 ounces. When worn, it protects you against piercing for 1, bashing for 9, slashing for 18, magic for 9, and the elements for 9 points each. When worn, it affects your damage roll by 2 points and your hit roll by 2 points. Only an elf could put it to use. Only a half-elf could use it. Note that it implies it can only be used by an elf, and only by a half elf. When I (an elf) try to wear it, it goes on then drops off, presumbably because I am not a half elf.
