WotLK Lost weapon

[Twostrikesdown]

Hello there. I have an inquiry regarding the lost weapon. So, I have downloaded WotLK expansion today, wanted to play it a bit. I logged on my main character, and noticed that my wrathful axe offhand weapon was missing. I know that I haven't sold it, nor destroyed it. Any chance to let me know what actually happened?

Nobody can know what happened to it but you.
