I wonder whether someone marked philmodjunk’s answer from 10/13/14 as “Correct” recently. The action of marking something correct isn't associated with a timestamp in the interface (though I imagine that it's stored internally).
I don't have the bandwidth to investigate this theory right now, but that's what I propose.
Seems like that could be the cause. Thanks for the reply. Yes I expect that pre Devcon you are a bit busy!
