Cipher bug

[Alhanelem]

Also check your other bags. Items don't just disappear without you actually trading them, throwing them away, or selling them.

You can also use /itemsearch "Cipher: Shantotto II" and the game will tell you where it is. If it's not in any non-NPC storage system this will confirm it.

There's also a somewhat recently added trash can feature that will allow you to retrieve items you accidentally toss (this list is forgotten when you change areas, so it only works right after you toss something), so if you do accidentally throw something away it is possible to recover it if you do so right away.
