Bug/Issue Duplicating tools and items from dungeon chests

To duplicate tools:

• Put tool in chest
• Second player takes your tool from the chest and keeps in inventory
  
• Sleep to next day
• The game (I think) recognizes the tool doesn't exist on you or in a chest, so it mails you another tool

To duplicate dungeon items:

• Player 1 takes item from chest
• 1 gives item to Player 2
• Sleep to next day
• Player 1 goes to the same floor, gets item again

To be fair, these bugs are very minor. I would hope that every player in the game can get the item out of the chest every 10 floors, and duplicate tools isn't really an issue.
