Atlas Tree Map Boss points missing

Hello I am blocked in the atlas tree's map boss part because of a bug.

I completed a T15 L79 map and got the 2 atlas points book as reward.

Then I started a T15 L80 map and encountered a double boss (Skeleton animal + Sorcerer). I killed the skeleton animal, saw the book dropping then the caster killed me before i can loot the book.

Now I do not get the book anymore on T15 L80 maps. Is it a known bug ? Is there anything i can do to get back these book ?

I'm having the same issue man i can't get the last 2 points which i think has blocked my char, i completed the copper and iron citadel today and both say failed due to adds not spawning or spawning out of the map or im just locked and cant prog.

Same thing happened to my character. I died on the same double boss but lingering sparks killed the boss and dropped the book.

I have completed multiple lvl 82 maps and my character is stuck at 8/10 points.
