Elphames Arena > Adamantium Throwing Dagger

My character "Moose" wields adamantium throwing dagger. Weapon type = throwing. He has skill level 2 of throwing. The dagger is acting like a normal dagger. It doesn't throw. Actually I just initiated a fight and clicked attack and my Moose just stand there with his adamantium throwing dagger. He did not move squares and he did not attack. What is happening in this situation?

The throwing dagger is behaving like a regular dagger

But when I wield it on MooseKing it does act correctly like a throwing dagger. Interesting
