Spinning Crane Kick bugged?

[fattz]

I tried posting in the bug wow forum and got no bites. Which kinda worries me. I have a brewmaster. and just in the last week or so, spinning crane kick has started somehow being interrupted or stopped prematurely. It only happens when im in combat with mobs on me. I can't figure it out. It doest happen every time i use it. but if theres 3+ mobs it happens quite often. Anybody else having this issue or am i all alone? =(
