Multiplayer Block Placing Wrong Block

When you are in multiplayer there is a bug after leaving multiplayer where when you leave the game, when you enter in again whatever your first item is every block you place changes to the first selected block. (Nexus 7 to Nexus 4)

*What I expected to happen was the right block to be placed

*What actually happened was the person connected had whatever the first block they entered in with to change to that block

Steps to Reproduce:
1. Join multiplayer and change inventory
2. Exit out of multiplayer
3. Enter in with same person and place any block
