Already had that happen once.
After the game, my tank had -1198 EXP.
So, I have been erased it.
But, the problem occurred again.
and now it has -930 EXP.
Before the last game.
50exp experience was evident.
My tank killed Infantry 13people. inside the game.
I have to expect that perhaps should be 70EXP.
But, my tank has -930EXP
Leaderboard rank in a ranked now dropped out of my tank.
And that, in-game does not take effect.
What do you think this bug?
