Entropy inexplicably drops from secure to weak

If I try to use this tool and set a password to …

some things drop in entropy for no reason

The password will gradually increase in strength until it is impenetrable … until you type that last "n" in the passphrase. Then it drops to weak.

The problem is with the unique function. For very long passwords, the uniqueness drops below the threshold. Our solution was to only run that particular check in a conditional. Essentially, we said if there are more than 12 unique characters, returns false. But, if there are 12 or fewer unique characters, go ahead and make sure there is adequate uniqueness (running the check that's currently in the code).
