Did they mention repairing saving materials in the patch notes somewhere, or has it always been in the game? I didn't find any indication of it when I looked, but maybe I'm blind...
I repaired someone's Bone Hora to get rid of a Bone Chip +1 for space, and instead I see the lines of:
You manage to save your repair materials.
You obtain 600 gil.
You repair the pair of bone hora.
You gain 22 goldsmithing skill points.
