It doesn't really matter - if you don't identify your set, naming the subject and the description that needs amendment won't really affect much. Some players see the name and have to select the description, some see the reverse; any given name or description could come up more than once in any given set. If you don't identify your set, you aren't revealing much. If it makes you more comfortable, you could wait 24 hours (although then some other set may well include the pairing). Or send a Pm to me, rather than posting here. The value of posting here is that others can see that the issue has been raised, so I don't get 150 messages about the same information.
Yesterday st least three different sets included Louis Leakey. And it may have been the correct answer in one of them, for all I know. Since this thread is mostly used by players who have already completed their set and are reporting an issue, it makes little difference. If anyone (really!) takes the time to check this out for clues before they play, they are taking this whole trivia thing far too seriously. It is rare for there to be more than one entry here a month - right now as I am overhauling the entries, there are more because of all the changes going on, but it should settle down again soon.
