The bug where if you attack a monster while in the air is fixed by any non-dc speedhack, but also accidentally by _fobos_ lovely multi-client that makes any speedhack non-dc, fix's the bug without having to be obviously speeding.
The only part of the bug that remains is if you jump to one height and fatal strike a monster at a different (usually lower) height. You still disconnect from this - I think it's a server side bug but I'm not sure.
