Hey there,

Please refrain from using all caps and spamming with exclamation points in future.

Also, are you sure you weren't accidentally dropping the diamond sword yourself? If not then it may just be a glitch, because it is highly unlikely that someone would go to the trouble of hacking your game just to make you drop items.
