I was playing a game before the compendium update and after it was over i restarted Dota to download the update. Once I returned I noticed I had received an item from the game I had played before the update. Bobusang's fist of the predator owl fist slot for tusk was my received item. When i went to preview it I decided to switch back to my Snowball Stinger, but my item had been replaced with a duplicate of Bobusang's fist of the predator owl so now I have two of them. I guess now I'm just wondering what to do next.
