When I looked at my Battle Log, I noticed that "Carel FF" just fought me and I had won the battle.

A few minutes later, my Battle Log of this battle had totally disappeared.  Normally, Battle Logs should not change, unless if the player asked for a Rematch, and a new battle result of Victory/Defeat/Draw would be produced.  In any case, the Battle Log of my battle with "Carel FF" is totally missing. This is proof of hacking.

"Carel FF" is hacking the signals (results) sent to Super Tank Rumble.  In the worst case scenario, "Carel FF" has hacked into your server (through your firewalls and security) and modify results.

Your immediate action to this matter is highly appreciated.

BTW, who on earth would believe Global Rank Player #1 Carel FF has medals 17,000+, whereas Player #2 has medals 3,000+.  This is statistically impossible.
