Forbidden Descent

On LFR, after defeating Eonar, I got credit. Yet, right after teleporting back to Antorus, the credit was lost. Finished the whole LFR wing and ended up getting credit for the last two bosses and not Eonar, thus not getting the achievement. Then I queued again. Same result. I also lost the credit I got for the last two bosses on the second run.

**EDIT**
My ticket on this received a response:
"Thank you so much for reporting this to us. Sadly we are not able to grant this Achievement at the moment. But the developers are aware of this problem and will resolve it as soon as possible. Please visit the LFR again after the ID Reset to get the Achievement."

**EDIT Jan 12th, 2018**
I got the achievement today on LFR. Just did it the normal way. The bug is fixed it seems.

Unless it's a hit or miss thing, the achievement is still not functioning correctly in LFR as of this moment. Just ran it on two characters, both only came out with Hasabel and Imonar highlighted in the achievement, Eonar was not. Ran a second time on one character, and as stated above, Eonar was highlighted until I ported back in which it unmarked itself. I also noticed that you dont queue for Hope's End in the LFR menu for these bosses, the menu has you queue for Forbidden Descent which according to the achievement list is a different set of bosses. Unsure if this might be part of the issue.

Still not working after weekly reset.
