I have a shelf block. When a player right clicks the shelf with an item or block it puts it in slot 0 and renders it like an itemFrame in the Shelf Model. If the the player has an empty hand and sneakClicks. It will pull the item out and give it to the player. Everything is fine and dandy up to this point. When the player logs off and then logs back in the item or block they put in the shelf doesn't render but when the player checks to see if there is an item by shift clicking. The item is pulled out and given to the player. If the player puts the item back in shelf everything starts working fine again.

 

Any Ideas with what the issue may be? Any help is welcome. If you'd like to see a particular class i can post it on pastebin no problem.
