There’s a known bug in Warhammer: Age of Reckoning that corrupts the player’s backpack window.

The corruption manifests itself in any number of ways, from a solid white box where the backpack window should be, to jumbled backpack interface elements with no items displayed.

I tried uninstalling all interface add-ons and re-starting the client, deleting the backpack interface files and letting the client recreate them on start-up, and reloading the UI using the “/reloadui” chat command while logged in.  Nothing helped.

Thankfully, weeks ago I had backed up the \user\Interface\AllCharacters directory in the game’s root directory prior to testing some interface add-ons so I had a back-up of the original backpack interface files.

The backpack interface files are found in the game root directory under:

\user\interface\AllCharacters\EA_BackpackWindow\

I noticed that when I deleted these files and allowed the client to re-create them on start-up, they were re-created still in their corrupted state.

To solve the problem, I overwrote the corrupted backpack UI files with the original ones I had in the AllCharacters Interface back-up I had made earlier.

So if you haven’t experienced the backpack corruption bug yet, back up the uncorrupted backpack UI files NOW!

Here’s a link to my fixed backpack UI files if you need them: EA_BackpackWindow.zip

Since these backpack UI files are from the default installation, obviously your backpack settings won’t be retained, but all your inventory will once again be accessible.
