In Ninja Burger, you can play the card Only A Test in response to failing a mission; it turns out that your manager was just testing you, and does not blame you for failing.
How does that affect the end-of-round honor bonuses and penalties? There's normally an extra Honor penalty if only one person fails, and there's an honor bonus if everyone succeeds. If Only A Test hid your failure, can you prevent everyone from getting the honor bonus if everyone else succeeded? Similarly, if your "test" is the only failure, do you lose the "additional" Honor even if you didn't lose Honor for failing the mission?
EDIT: Full text of Only A Test:
Play this card immediately after you fail a mission. It was only a test! You suffer no loss of Honor or other penalties. Your manager made the task very difficult in order to evaluate you and sharpen your skills, and he does not blame you for failing. You cannot use this card to save yourself from a failed Errand!
