I was browsing some replays and noticed a T14 with over 7k dmg, which sounds pretty awesome. But after checking the details it turned out to be a match in a M48 Patton.
Not only the tank is wrong, but also the time and date. All the other information seems to be correct.
I checked some other replays and the same thing occured. Many times the T14 was displayed in the heavy section and I also found a T62A labelled as T-34.
