Can't buy zeta replica?

[Inzoum]

Wait....so if I already did the Vital Title quest and turned in my zeta, I can't get a replica of my Zeta weapon?

You can, this is the normal way of things. The dev post was addressing the particular case where players would complete their zeta, but not finish the quest (talk to npc for last cutscene), and then proceed to destroy their zeta for the anima quest. Doing this left the quest "the Vital Title" incomplete and therefore didn't set the flag needed to purchase the replica. This just means there will soon be a fix for those who broke their quest and their ability to purchase replicas by skipping some steps.
