Not sure why my NPCs are falling through the ground in my level. I have a collider on for the ground, on the NPC, and I even tried a rigidbody and freezing the constraints of my NPC. Not sure what the cause may be. My NPCs do have animations on them, but nothing that should be causing them to fall.
It looks like they are going to an animation state that does not have an animation assigned. Make sure all states in mecanim have an animation
