Same thing happened to me with PLD Valor Cuisses. My bug report was accepted and is currently with the investigation team. My prob was gear disappeared on gear swap inside turn2.

This was four weeks ago. I'm guessing it is happening to a lot of players and with limited resources it is sure to take some time. My main gripe was this is my accuracy piece for coil and leaves my seriously gimped at the moment.

Hang in there! I have my fingers crossed that it will be returned soon also or 825 Myth down the toilet.

This is bad enough but my biggest fear is that is happens AGAIN since it is already noted as an accepted bug.

Give it a few more weeks.
