Right now you can only do one of two things.
- Don’t play anymore knowing this could happen at any time for any item(s) or character(s).
- Play expecting this stuff to happen and learn to shrug it off… cause blizzard won’t take any responsibility for deleted content… even when they are the ones who caused the deletion from bugs/issues.
Sorry to say, but your options are what many of us have.
I lost all my stuff due to some bugs… which haven’t been fixed yet… So I contacted blizzard.
Here is what they told me.
Basically they take zero responsibility for their actions.
It’s heartbreaking I know.
Good luck out there traveler.
