EDIT: Fixed Today
Some chests are bugged in Pandaria and you can loot the gold infinite times.
Just loot the gold but not the item in the chest and hop from realm a to realm b
The gold will reset after 5-10 minutes and you can loot it again on the realm you have already looted.
Notice:
Fill up your bags with items to get not failed on this progress.
If you loot the item, the chest will disspawned.
Turn "Auto-Loot" off.
