I've also seen this happen, it's quite anoying.

In addition I have attached a replay with exactly the opposite problem. The blue player does an opening move that starts with a jump and lands almost perfectly back on his feet, only to be DQ'ed incorrectly.

EDIT: I've just seen the thread that explains the foot though floor problem here: http://www.toribash.com/forum/index.php?topic=182.0
