Previously when we encountered the similar bug, someone said in a post that you can actually change the item back to normal in the game by dying in the game with the items equipped (aka reduce their durability)...then do not repair the items...and list them again in AH. That should fix the problem.

I have tried this method. It works! but still have one or two items not working.

How do you know your item has this problem? If you wana list the item, the troubled item will take very long time to load into auction tab. and usually the game will show "auction house busy and will list it later..." and it also take very long time if you cancel it. take very long time to return to your stash.

BTW, i got an item back from the expired winning bids problem after a few days.
