In the CBT 4 was a problem and it has already written to the forum testers:
In the "Companion" took off Chocobo ammunition from Garnd Company (FF XIV ver.1.0). Armor has disappeared and more than its nowhere to be found - not in invenotre, not armory.

ustomer Service replied as follows:
"Unfortunately, we are unable to assist you with your request since it falls outside the scope of our services (In game content question)."

How do I get the armor for the mount back?
