Thanks @AdamWARREN for doing that research and sharing the results you found. The page you found refers to New Quizzes, which is where all of Instructure's quiz-related development work is going. If your question about blueprints/outcomes relates to Classic Quizzes, Instructure will only work out bugs. It seems reasonable to me that this is a bug, since it works in one situation but not the other, so I suggest reporting it to your local Canvas support team.  It would be great if their vigilance extended to the Canvas Question Forum, alas it does not.

I’m going to mark this reply as a solution. I realize it does not solve your problem, but our colleagues who face a similar challenge will know how best to proceed.
