Memory Eater, where is the Fragment?

Hi,
I'm currently searching the Memory Fragments and i have a problem.
In my atlas, the Desert Spring map is shown as containing a Memory Fragment and occupied by the elder.

So i buy it, 6 Vaal and i'm not rich so it's a cost, and complete it in normal rarity. Nothing happens.

I got all the others fragments in Rare maps, so i buy it again, 6 Vaal, alch it to get the rarity and complete it again. Nothing happens.

I tried it again a third time, with the bonus objective this time so 6 vaal+ 1 alch+ 1 vaal to have a corrupted rare and one more time nothing happen.

I don't have time and currencies to waste anymore so please tell me where the Fragment really is, the bug stole me so much i deserve this at last.

If someone know how to add screens to the post and tell me, i'll add some. My bug report number is 1 489 036 741.

You need to defeat the four elder guardians before you can fight the Elder himself. The fragment comes from the elder fight, not the regular boss that you usually have on the map.
