People being hacked since the last Server Check.

Alright so some days back I bought an elemental wand (lv70 blue one), and today I checked the inventories/bank on all of my characters and it's not there. I bought it for around 45mil so it's not much of a loss but it's still sort of sketchy. None of my other stuff were messed with (chairs, mesos, etc).

So I'm wondering, was my account hacked, was there some sort of rollback in the last week, or did the elemental wand have some expiration date I was unaware of..?

A lot of channels been crashing lately. It might be lost in one of them (rollback).
