This is odd because the Changes to Profile Van_Staden-34 show you initiated the change this morning. The Changes to Profile Van_Staden-195 show you initiated a change this morning. And your contribution list shows this as well. And this mornings match has the exact same comment as on the Jun 4th Matches you posted. This mornings Merge Post is also the only activity on your Contribution list at that time. You had activity 5 hours before and 4 hours after. Just that one lonely activity.
So if not you Philip, then you have good question. If it was a WikiTree bot that did this, it would say the bot initiated this mornings post so I don't believe a bot is responsible. I am at a loss. Ghosts in the machine???
One thing, if this happens again, please use the tag MENTORS in your G2G question, bring the big guns in.
