Lumpyhumper is his name.
Told him to meet me at the Flight Master in Stormwind. He agreed upon that since i was going to boost him in Deadmines.
But the odd thing was, i could not see him on the map when i clicked M. However i could still track him on the Minimap. I went to the Dwarven District and i noticed something REALLY weird..
It looked like he was moving through walls and buildings. And no he was not on a Gryphon. He was running at normal speed and he even made it to the Flight Master BEFORE ME from the Dwarven District..
This makes no sense at all and i do not have any screenshots of it. However i hope if he is a hacker, the anti-cheat system can track him and his logs to ban him.
