I was browsing recent questions on Earth Science, and came across this question, which is closed as a duplicate of this other question. However, the latter appears to be a deleted question.
Now, I'm not making any determinations of quality regarding the first question, but a question being closed as a duplicate of a deleted question feels "off" to me.
In this case (or similar), should a different dupe target be identified, the question be considered for reopening (if it's of sufficient quality), nothing at all, or something entirely different be done?
