[Teek] Key of Swords (Plane of Sky Island 1.5) bugged

On Teek, characters who are not flagged for the Noble Dojorn island (commonly referred to as island 1.5), which normally requires the Key of Swords, will automatically be flagged for it once they zone up to island 2 using the Key of the Misplaced. You will not receive a message that your character is flagged, but you will in fact zone up and have Key of Swords checked on your achievements.

I have been able to replicate this on three characters on this server, none of which bought the Key of the Swords nor turned in the Miniature Sword. As a matter of fact, I turned in a Miniature Sword on one of the characters and Sirran accepted it, but nothing appeared in my inventory.

It only says Key of the Misplaced would be checked on your /ach.

It will automatically be flagged indicated there is perhaps no physical key

Was it checked?

There was a typo in my post where I referred to the Key of the Misplaced achievement instead of Key of Swords achievement. Thanks for the question - I have edited it for clarity. When clicking up to island 2 with a Key of the Misplaced, it is both checking the Key of Swords achievement on my keyring *and* giving me access to island 1.5, which is not intended behavior as far as I can tell.
