A blooper, a continuity problem, and a behind-the-scenes anecdote are not the same thing. The source brings them together under a nostalgic headline, but they require different kinds of support. A visible editing mistake can be checked against an episode. A story about how a costume was prepared depends on production recollections. An account of a personal relationship concerns real people beyond the fictional setting. Keeping those categories separate makes the discussion more precise and more respectful.
