Hope mo'bends mod can fit headshot mod,
maybe by change hotbox or some other way,
because mo'bends change animation but not change hit box,
so play with headshot mod will have some problem.

if really fit headshot mod, i think some Zombie Apocalypse modpack will become more real.

I was wondering about this when I installed both of these mods too, i just aim a little bit high and it seems okay and still get headshots, but yeah.
