Sorry to hear about that… Yeah… lots of items can just ‘poof’ for no reason at all… Bugs on their end are causing it.
I lost all of my stuff cause of these issues… I contacted blizzard… they won’t take any responsibility for it…
So you can play knowing some/all your stuff can vanish and it’s just Gone Gone…
Or not.
It’s a bummer seeing so many people lose so many items… Just a soul crushing pain… even more when it’s a whole character that’s been deleted.
