Issue (The better the description the better i can solve the issue):

When you use Primitive mobs alongside Improved mobs, the skeleton warrior's bow animation seems to be broken. It basically just stands still while the bow shoots. IM seems to be the cause of this

Steps to reproduce:

1. get primitive mobs and its dependencies alongside improved mobs
2. start up a minecraft world
3. engage a skeleton warrior, and pay attention to how the animation is basically broken
