A question was posted very recently about monetizing magic in a Renaissance Venice. I commented to suggest some development that might avoid Idea Generation closure. The OP replied with thanks, and I gained a bit of rep. But now the question doesn't exist. My rep history retains it, but the link is dead.
What does this mean?
EDIT: Correction. My history retains that the OP said the comment was helpful, and said thanks, but I did not gain rep from this. It's inbox that retains the entry, not the rep list. Not that it matters -- the answer below is perfectly sufficient -- but I thought it best to clarify for the record.
