I just looked at the leaderboard for the first time, and then played about 4-5 PvP, winning them all, but when I refreshed the leaderboard, my win number only went up by 1.

Edit... Something seems wrong with the leaderboard now that I'm paying attention to it. I just won 2 matches in a row, and my "total wins" went DOWN by 1...

Edit again: Just won another match, checked the leaderboard and my total wins went DOWN again by 1. Also total fights did not increase. Please fix...

3rd edit: Took a break, made a new character & the leaderboard was stable at 101 fights / 53 wins. I then played 8 in a row, winning 7 and losing 1, so my totals should be 109 fights / 60 wins. However right now my stats are 109 fights and 58 wins. Where did the 2 missing wins go?
