Missing the 5th key fragment of Fairel's Tomb

Is it possible to sell one of the key fragments? I've been through the five prerequisite tombs, several times, and definitely missed nothing. I've even tried selling one of the four I have to see if it's possible to sell, but I can't find them in my inventory! What did I do? How do I find a fifth key that I've already found, but somehow misplaced?

Are you sure you went through the five prerequisite tombs? You might be counting the westernmost cave symbol as a tomb when it's not; it's a ruin and is not part of the quest.

Here are the locations of the five tombs housing Fairel's Tomb key fragments:

As I said, the westernmost cave symbol depicts a ruin and the easternmost is Fairel's Tomb proper.

Been through all the tombs 3x's now and there is no 5th key. Found a bunch of statuettes but there are no key fragments left to claim. Glitchy game.
