#

vanilla method "knockback" in "EntityLivingBase" class has a bug, when both xRatio == 0 && zRatio == 0, will cause creatures be attacked disappear, this issue happened in dragon weapon knockback.
How to reproduce?
use a fireblood saber and use /summon commnad summon a husk(or any other creatures), and hit it with that weapon instantly, the creature will disappear instead of being knockbacked!

events.onLivingKnockBack(function(event as crafttweaker.event.LivingKnockBackEvent){
if(event.ratioX == 0 && event.ratioZ == 0)
  event.ratioX = 1;
});

this puts kb dir in +x now, you could ofc also randomise it
