Lost Thunder Shedinja Bug

When attaching shedinja from your bench to one of your Pokémon as a Pokémon tool card, any energy are meant to be discarded. However, the energy instead remain attached to shedinja. While shedinja is attached to another Pokémon, these energy are completely invisible, however, if the Pokémon shedinja is attached to is knocked out and shedinja is brought back onto the bench by an effect such as ninjask's molting Ability, the shedinja will be taken from your discard pile and placed on your bench with the energy still attached to it.
