Bug I found during multiplayer

In order to reproduce what we did all you need to do is connect two 4th generation iPod Touches over wifi in a survival game and they each need 6 wood and one workbench between the two of them. Then all you need to do is craft, place, and destroy a door. When you break the doors, you will receive two door drops instead of one. This isn't too major considering Johan hasn't implimented a recycling GUI block, but it still is a bug nevertheless.
