When mojang added the internal server in 1.3 it introduced horrible lag in mobs and other stuff when it was instant before, this mod fixes it to restore it to its pre 1.3 glory with fast knockback on mobs, still keeps the interpolation though for smoothness and to prevent any buggy looking animations.
This mod due to its technical nature, could cause incompatibility issues or crashes with some other mods.
