Camel's torso animation tilts in a more jittery lopsided way than originally

The Bug

Before the Camel's walking animation was changed, its torso tilting had a nice, smooth animation where it tilted back and forth. You can see this in the snapshot it was originally added in:

But not in more recent versions, the torso has this odd one-sided snapping, as if the animation broke. It doesn't look like an intentional part of their walk cycle change to me, so it could be a mistake/oversight/bug. It can be compared with the old one here:

It's subtle, but watch the difference in the way the torso rocks side-to-side

Steps to reproduce:

1. Spawn a camel in the snapshot they were originally introduced and observe their walk cycle while riding. Its torso with tilt in a smooth manner
2. Do the same in newer versions. Observe how its torso tilts in a more crooked, odd way
