When you click on a chest, whether you or a friend made it, it will open and show its inventory like normal. The bug is that when the WiFi visitor places stuff into the chest and close out, it will not keep those items in the chest. Also if the map owner places things into a chest for others to use or take, they can take them but it will duplicate the item and keep the original in the chest. So I can place a diamond pickaxe in the chest, have a friend take it out, then I can take it out again giving us both a pickaxe.

What I expected to happen was...:
Either myself or friends could place items in the chest for everyone to take or use

What actually happened was...:
Friends would place their items into a chest and open the chest again and the items would be gone.

Steps to Reproduce:
1. Create a chest
2. Have a friend join your map through WiFi
3. Get items to place into the chest for both the map owner and the visitor
4. Have each person place their items into the chest and then leave the chest
5. Reopen the chest and notice that the map owners items are still there, but the visitor's items are gone
6. Have the visitor take the owner's items out of the chest then close the chest
7. Have the map owner look in the chest, their items will remain even through the visitor took it.
