I started an egglocke and picked a random pokemon from the first box as my starter. It happened to be a Zorua, which has the Illusion ability. When I use it in battle, the name of the illusion is incorrect.
Clearly, the name displayed for the illusion should be "Fun Guy" and not "Egg Token". Note that I have not changed any of the names from the ones pregenerated for each egg. When I changed the name of Fun Guy to something else, the name of the illusion is correct.
