thought maybe it was a visual glitch with her profile so I checked on my iDevice and asked 2 other people to check, all showed her as last online 7 hours ago
she came online about 10 minutes after my last post though
also asked several other PKers who I saw very active throughout the day about the leaderboard reset and they all said they were definitely reset overnight
no idea how anyone naturally manages 3841 kills in an hour, literally over 1 kill per second for an entire hour, on a Friday at 5 AM when less than 1500 are usually online
still doesn't make sense that no one would have noticed her way above everyone else on the leaderboard for the 7-hour period before I noticed though, not sure what happened
