Item disappeared - need help!

Hello!

About a week ago my item Armageddon (2hand sword) disappeared from my bag and so did the transmog on my actual weapon. I have had the item since 2013 (bought it at a vendor, can't remember where, but it was before the warmane merger). When AT merged with Warmane there was a new transmog feature, as you may know, which allowed you to transmog items based on their ID's. Anyhow, I transmogged my Shadowmourne to Armageddon based on it's item ID. A couple of days later they invented a new feature which allowed you to transmog based on the items you have in your bag. In this time frame the transmog was gone when I logged back in one day, and the item, too. I have not removed the item from my bags nor have I removed the transmog. No one else knows my account besides me.

Help is deeply appreciated.
