  1. Shared Item Cheat Detection [Star]
  2.  
  3. This code will detect when a player tries to obtain a Shared Item, but the item they intend to cheat already has it's maximum amount in play. The code will also detect when a player obtains impossible item combinations. It will display the slot of the offending player in the milliseconds of the timer, accompanied by a value denoting the reason.

  1019. - This code relies on a specific value in the ITEM Packet. Due to the nature of how network traffic is sent, it is recommended to have all P2P connections set up (NATNEG complete).
