Steps:
1. Get two of the same piece of gear with the same quality, but with different materia (or one with no materia).
2. Create one gear set with one piece and another with the other piece.
3. Switch between the two. After switching the gear that was equipped previously remains equipped even though the gear in the second set was saved with different materia.

Please look into this, it's a problem for people who wish to spiritbond one piece of gear with no materia to convert and another of the same piece with expensive materia for regular use. Also people who have different gear sets with materia that maximize different stats such as crit, accuracy, etc.
