Hi!

I was doing A Relic Reborn Quest, I gave my Unfinished relic weapon to the NPC and I was on the way to kill Ifrit Hard Mode. Later i saw my quest was on the step "obtain a timeworn..." the first step. I dont know when or why but my chain has been broken.

I have spent several time, gils and effort to restart it again... So please, i hope you can restore my quest.
