Fox 'stutters' when running from player.

Foxes tend to run from players from a certain distance, but lack any radius to which the fox will run away from the player further than that radius to be "safe" from the player, meaning foxes continue to start and stop running as the player is walking towards them. The starting and stopping motion can be more obvious if the player is imbued with slowness, but because of the motion of the fox, it can be subtle (smooth deceleration and acceleration)
