Backpack disappears after being placed in slot and exiting the GUI.

[GoogleCodeExporter]

What steps will reproduce the problem?

(I am unsure how to prompt this bug/issue, but when the issue is prevalent...)
1. Get Backpack.
2. Insert into slot GUI.
3. Exit GUI.

What is the expected output? What do you see instead?

The backpack is supposed to be wielded; instead, it disappears.

What version of the mod are you using?

1.7x 2.0.0

What version of Minecraft are you using?

1.7.10

Are you playing on a server? If so is it a forge or MCPC+ server?

Well, single player and LAN. 

If you have an error log please provide me with a pastebin link:

N/A

Please provide any additional information below.

This only occurs for one of my worlds, others work fine.

In the backpack folder in the config, i noticed that each backpack has one DAT 
and one DAT_OLD file. After this bug started occurring, it would make the DAT 
file but not the DAT_OLD file.

My UUID is the same in each world, so that is not the issue.

Please delete the player folder inside of the backpacks folder.

That he only creates a .dat file at first is normal.

When he overwrites the file with new data he moves the old one to .dat_old and 
then writes the new data in .dat. If the .dat is corrupted he has the 
(possibly) working .dat_old as a backup.

If it still doesn't work google for NBTExplorer it is a programm that is able 
to open and read the .dat file.
When you open the folder and expand the file it should look like in the 
attached image.
