Power users may have experienced this situation before: They see a question that’s clearly a duplicate, so they hunt down the duplicate target and close the question. It’s only then that they realize that the question was improperly tagged, so they cannot hammer it, although they expected it to work.
This commonly happens to me personally when closing Python questions, which then fails when the question has a versioned Python tag but is missing the general Python tag which I have the gold badge for.
