Cren, I believe that you did right reporting it, but you shouldn't (and no one should either) insist on the matter.
The titans will do what needs to be done.
It was a bug exploit, Tim said. It is fixed.
Roleplay it as a magic event and move on. You (and no one either) will gain nothing worrying about this. The game will not role back. Nothing good will come from asking for a punishment for that player. If he/she is a cheater, he/she will cheat again and will eventually have a punishment at some point.
In mean time, we have fun playing fair
