Users have expressed much concern over locating crafted kegs and we have found the answer! Crafted kegs are a decoration item and can be located under the "DECOR" section of the inventory.
The CastleVille engineers have crafted hundreds of kegs in an effort to investigate the problem of "missing kegs" after crafting. It has been discovered that everything functions normally. Now let's just hope these same engineers can find a belly for all the extra crafting! Good luck :)
