And guess which stage I abandoned at!

THE PART WHERE I NEEDED OIL!

Quite literally THE END of the entire quest, and I accidentally deleted it when clearing out unwanted Levequests (I was levelling Miner and accidentally took out the Combat Leves).

Why, Square.... Why? Restoring quest progress isn't something they can do, so I need to start again. Why make the Relic quest abandonable? There's lots of quests out there you can't abandon.
Why make the interface snap back to the first quest in your quest log every time you delete a quest?
Sure we have to read them to make sure we're deleting the right ones, but mistakes are gonna happen. And this isn't a simply "Woopsies" mistake, this is a "WEEKS OF HARD WORK AND TONS OF GIL WASTED" mistake.
; o;
I just... I just...

They need to break the Relic quest chain up into separate quests.

I think I need to lie down for a few weeks and ponder life.
