On Monday I had 2 Memories of Vlast - one earned from the achievement and one bought on the Trading Post. I know for a fact I had both on Monday because I had been carrying one in my inventory (waiting to use it for something) and I put it into the bank to make sure I didn't accidentally sell or delete it during Halloween. I discovered it wasn't possible to stack them, so I put it into a different row in my bank (which I always keep organised) to the first one, along with other items I normally carry but temporarily stored for Halloween.
Today, following this topic I noticed it's no longer possible to buy them from the TP and went to see if mine were tradable so I could send one to the OP. That's when I discovered both were missing and there are two empty slots in the middle of rows of items exactly where they were.
I'm absolutely certain I didn't withdraw them (and I would have moved the other items over if I had) but I've checked both characters I've logged into over the last few days just in case and neither Memory is in their inventories.
I asked my guild and several other people said theirs were missing - in all cases they had stored them in the bank. One person reported theirs was still on the alt who was holding it, but it seems like anyone who had it in the bank has now lost it.
Considering this item was only obtained from an achievement I'm very concerned about this. I'd really like to get it back, since there's no way to get a replacement.
"You can run like a river, Till you end up in the sea,
And you run till night is black, And keep on going in your dreams,
And you know all the long while, It's the journey that you seek,
It's the miles of moving forward, With the wind beneath your wings."
