PoE2 Boss atlas point bug

Hello, I have an issue with the acquisition of map boss atlas point books. I am currently stuck on 4/10 points for the boss tree and the books no longer drop. I have killed multiple bosses in level 81 maps with 6 mods and one boss in a level 82 map with 6 mods. All map clears done solo, not in a group. The books just do not drop.

Killing the Arbiter enabled the boss books to drop again. So the issue has a workaround.

i'm stuck at 2/10 points



i added 3 tablets into one tower to get many bosses around me, i keep knocking those out but i do not get any points what-so-ever.

is this the culprit? do bosses added by towers not count towards atlas points? if so pls add this crucial info to the tooltip.

thx for your effort
