Possible hurl bug?

Someone deftly catches you in the throat with a throwing dagger! Someone's hurled dagger scratches you. Someone has some small but disgusting cuts. Not sure if this is more of a gameplay issue. But I can't say I remember hurl lasting that long. I know I would have killed Cabdru that one time if I had 4 tick silence! Skill: 'silence' for 3 hours. Skill: 'hurl' modifies strength by -4 for 3 hours.
