From my first posting about this problem on June 11: I paged "through my entire list of contributions. I found a big gap. [which was confirmed by T Cassidy] According to the list, I made no contributions between February 1 and April 10, 2016."
Chris, that's zero contributions for all of Feb, all of March, and a third of April.
Yes, I can tell you EXACTLY which profiles i was working on during that time: ALL OF THEM.
I don't know what WT considers to be a "contribution", but surely creating a node is one! Do you have a way of seeing the creation-date of a profile? If so, sort my watchlist by creation-date. Were any of them created during that 70-day span?
