Catch bug (is this new?)

[Marko pro]

The knight could immediately catch me after only getting hit once by Julian's projectile

there it is...

Is this new? I've never seen this bug before, lol, and it was annoying . Maybe someone know some mechanics of it? I don't have any idea what can cause it to happen, but maybe there's something to do about that Knight catching me right after I got hit.

EDIT:
ah... the pic didn't work.. I removed it. I'll reupload and put it here once it's done.

OK I have put the youtube link or here it is: http://www.youtube.com/watch?v=umeyiZtgZEI

Do you know what you mean when you say bug.Bug is something unpossible.This possible!!!!Someone can catch and other man can punch you or kick you.Think before posting.!!!!!
