2 days after melding materia---1st and only meld of one item on 4 different armor pieces---I go to change jobs and the job list states ALL materia is invalid and unrecoverable. this happened to both the gathering and crafting classes. however only the gathering materia is now listed in red while the crafting item still appears as good but the job class is marked just like the gathering and the same message "eqipped, but materia and aetherial attributes could not be restored" . what gives and how is this fixed? and further what could possibly cause this?
