Crafting Signatures Disappear? Is it supposed to?

My good friend crafted me some gear, and while it used to show his character's name at the bottom once I hovered over it, it no longer does. :(

Does the signature just disappear after awhile? I've asked others, and after looking at their items, they've also noticed this. Is this a bug? Do signatures just get lost over time?

Might be something to post on the bug report forums. Sounds like its a bug to me but who knows.

It's a bug. The signature is actually still there (you can see it on the Lodestone), it just doesn't show up properly in-game most of the time.
