This will be hard to describe but I'll describe it the best I can. Whenever I play games involving pvp (usually VampireZ) I can see this player following my trail after I kill someone sometimes. Strange thing is, they're not there. Its just an image. It seems like it only happens to me and its been happing for like a month. I cant tell if its my minecraft or just that gamemode. PS, Whenever I try to attack them, the server thinks I have hacks.
Woah, that's weird. The only logical reason I can think of is that the server that you are on has a plugin, although VampireZ has nothing of that sort. Hmm...
