NpcAnimation::setViewMode makes a call to the character controller, in the
mechanics manager, to forcefully update the character's state. This in turn
makes a call to the player's old NpcAniamtion object that was just deleted.
The mechanics manager will eventually remove and reinsert the player, so the
old character controller will be removed and a new one will get the right
Animation object again, but not in time for the setViewMode call.
There's many factors that all contribute to this run-around, which needs
discussion on how to best fix.
