Full context i do not remember if i got a Cs or not
I looked through my storage and Cipher Of Prishe's Alter Ego II is no where to be found

I cannot complete the story without it and the quest won't finish and i don't know what to do to fix this.

I tried emptying my inventory and talking to the Mystic Retriever in Port Jeuno near the guide stone but no item was given.

I am fairly sure i had it stored in white gate storage and when it ran out it deleted my items stored there.

I request could you please reset my quest line back 1 quest or even just reset this quest for me?

Again the quest name is
Rhapsodies of Vanadiel Mission 2-3

I had forgotten allot about FFXI while i was on break and didn't know how to get to white gate as my teleport had been removed i am guessing with an update of some kind.
