Bug with anticipate/

According to the helpfile sometimes when you successfully anticipate an attack you get a counterattack. However it doesn't seem to work. Here's a snip: You foresee a disgusting, rotting zombie's claw and move yourself to safety. You foresee a disgusting, rotting zombie's claw and move yourself to safety. You anticipate a disgusting, rotting zombie's bash. You deftly return a counter strike! A disgusting, rotting zombie's claw wounds you. A disgusting, rotting zombie's claw injures you. A disgusting, rotting zombie's claw mauls you. A disgusting, rotting zombie dodges your punch. Your punch devastates a disgusting, rotting zombie! A disgusting, rotting zombie is writhing in agony. As you can see there I get an echo that I return a counter strike but I don't get any attacks. (I'm fighting two zombies there so the second zombie hits are the other mob) This could just be an issue with mob attacks that happen mid-round. I haven't tested this on a player yet.
