Quest Glitched - The Lost

Warning, this post contains spoilers of the quest.
What happened step by step:
I started the quest, got 5 letters. Dropped them(because of full inventory), found 1 NPC, did /fixquests, gave him 1 letter, dropped other 4. Went to 2nd NPC, tried /fixquests, did not work. I have tried checking all my inventories(bank, other classes) theyre all without the letters. What do I do now?

 

Basically, you can't do anything. The letters from The Lost don't get returned from fixquests, which leads to this problem. I don't know if/when it will be fixed. It happened to me too, the server restarted as I talked to an npc and I still haven't completed the quest at level 91. I was pretty annoyed, too, I needed a bow upgrade and had an air bow for level 84 which needed The Lost as a quest req. I couldn't use it, had to find a different one :(

 

Currently you'll be stuck with that quest uncompleted until the admins fix the bug. The only way around it is getting the letters from another class, and then transferring them to the one you need them for. (but then your other class will need the letters so you will either need to have 1 class which hasn't finished the quest or just delete that one, but i wouldn't do that to a level 80 class)

So in other words, rip.
