Fly Animation Poses Not Working

[Guardian]

As of this new patch. The fly animation poses no longer work to cycle.

Using this:
/bind z, "e flypose4$$e flypose3$$e flypose2$$e flypose1$$powexec_toggleON Fly$$autorun 1"

When flying and pressing the z button, you would cycle through all four poses.
With this patch, you can only go to fly pose 4 ... continuing the press the z button, it does not move to next fly pose.
