On player's page count of deaths in "Statistics" section is not equal to sum of deaths in "Weapons" and "Vehicles" sections ("Total" row). I checked top three players and all three have "Weapons" + "Vehicles" > "Statistics" deaths. One of them played 14 hours ago, others are playing right now.
Same is for "Kills", except one player got "Weapons" + "Vehicles" < "Statistics".
