This is a bug in how `wAttackMissed` is never set by BeatUp, even when none of the 'mon have been able to attack (due to being fainted or having a status effect), the King's Rock may activate.
This bug is caused because Beat Up never sets `wAttackMissed`, even when no Pokémon was able to attack (due to being fainted or having a status condition).
