Inaros 3rd challenge bug

[Mercurial_Umbra]

So I killed the last of my denial bursas (what I had for my 3rd challenge) without the quest set to active and now the urn is gone from my liset (where you normally check the progress) and it keeps saying complete the 3rd challenge although I've already done it. Any help/fixes?

my urn reappeared and now i have to kill 2 more bursas, but at least it fixed itself, I was about to submit a ticket when I noticed it.
