Only one of my chars (BK named XichLong - empire x500) after reset. I'm loggin a few minutes and receive the notigication "Your attack speed modified. Speed hack" then my char was disconected.
I'm not cheating, here's my prove: Wrong speed hack notification. Disconect. Empire sever 13/4/21 - YouTube
As you can see, i dont run any 3rd parties software. It's clearly a game bug or some thing. Please check it out.
