Currently, when a user creates a Pokemon with multiple duplicate moves, the validator doesn't say anything is wrong and just removes the duplicated move from the user's moveset automatically. I've definitely made the mistake in the past where I quickly make a Pokemon's set, don't realize I really only have 3 moves, and don't figure it out until the battle. This also fixes an issue with automatic move changes (i.e. Iron Head -> Behemoth moves) where a user accidentally adds both Iron Head and the Behemoth move without realizing Iron Head becomes Behemoth Blade / Bash. This way, the mistake is exposed at the teambuilder level, so they don't think get confused about why a move is missing.
