I was on the long 9th floor layout when I got a speed blessing so I popped on bird poly and took off like my pants when the wife says Lets Go.
Was half way across the floor and I got a "Hello" (or something) in chat and was moved back to where I started.
Got another one on another floor, killed all the mobs like an absolute mother fucker, ran a bit, and was moved back.
Seems like the antihack stuff is messing with the buff.
