I've checked your "Un-deliverable through same Playonline account" thread within this forum for the Shaper's Shawl. It was not listen among the items (I used the CTRL F function). However, I was severely disappointed when I was unable to send the item "Shaper's Shawl" to my main on the same Playonline account.
Either this is a bug or your moderators have neglected the contents of the thread.
I am disappoint.
