BW macro failing?

[OuterChimp]

So, my human monk is level 17 or so. I've had great success with using a BW macro all the way till now.

Now he is fighting the Scarecrows in West Karana and I seem to be getting the "you moved" message as soon as I hit the macro.

I only occasionally got that message before, but now when fighting Scarecrows I get it right away.

Do Scarecrows, and i assume other mobs, just push you just enough to make the bindwound not work?
