How can a player with 120 battles can have just one tank?

MrConway: So you guys actually piqued our curiosity with this case and we had a little look at what exactly happened.   As many suspected, the player's account was indeed wiped, which removes all game progress, and credits. His public stats are however buggy and I can confirm that he played more battles than the ones shown.   It turns out that if a very skilled player really wants to level up and uses premium time, XP and free XP boosters + a 2 x XP for every win event, it does not take long for him to get battles together.
