permanently stunned by enchanter mob, bug?

[DMN]

I just got killed by an enchanter mob who hit me with anarchy and then my character ust sat there running in place for the next 15-25 or so seconds hile i was beat to death? umm, wtf? He cast nothing els on me, only anarchy. the log clearly shows it says "unstunned" but i was never unstunned and could not move or cast spells, just derpilly run in place. Is this a known bug or something?
