Guildhall items disappear

[Futumsh]

Oh.
That make sense and could confirm the disappear of Goblin Vault.

...but the Cage was mine, I looted and I put in GH.
Why on Earth (on Arlor) it vanished?

When you place an item in a guildhall, it isn't necessarily yours that's being placed, unless there are no other guild members that own an item of that type.
