Expedition no longer drops logbooks; even with full Atlas Tree Passives + Scarabs.

Bug: Logbooks are not dropping under certain (unknown) circumstances. We ran this on two different Atlases, two toons, joining each other for the Expedition encounters then going back to popping more in our solo maps. Both players had every Expedition Atlas Passive going. Polished scarabs or greater were used on all maps (t15-16), began filling the rest out with Sacrifice Frags instead of other scarabs because of the no loot problem and to test it all day.

Between two players, and 100 Polished Scarabs + Passive Tree, we had literally ZERO logbooks dropping in 110% quant red maps that we can barely do.

Yesterday, we tried to switch to an Expedition farming strategy. My boyfriend and I did this, we also cannot map together as the map mobs are too hard so we compiled this playing side by side IRL but unable to play together in game. I'd also add that drops for 2 players in a party have no noticeable difference; please don't call being a two person party "juicing" its just Portal sacrifice and becoming offensive. We both fully spec'd into the Atlas Tree in Expedition. When it came time to run the Expedition encounter, though, we would come to each others' maps and I would clear out the area as my boyfriend's high investment character is dying constantly and his exp bar is perma 0%. He has put about triple the currency into his toon, but that is for another post. This is about the fact that Logbooks ceased to drop entirely, also the amount of untradeable Expedition currency to use with the merchants is so hard nerfed it makes me want to cry. I have never done Expedition as a strat before (I'm desperate); but am quite familiar with it and have been changing strategies daily to try and understand what we are supposed to be doing to progress. I used to run Expedition scarabs last league with 0 Passive tree investment when Gildeds were lying around and I would do quite well. Now with full investment I get basically no loot except for piles of bad fractured items that no one is buying, most not even worth ID'ing.

We went through almost 100 scarabs on our day off. Two people, blasting fully fragged maps t15-16 (we started out with Delirium Orbs, too, but those are not worth running and we stopped halfway through as we went broke). The 100 scarabs were Expedition Scarabs. Again, we were BOTH fully specialized into Expedition on the Atlas Tree and using Scarabs and rolling our maps with frightening mods because we are desperate for quant. So it's not just 1 person. Add Expedition to the list of bugaboos...

I do not understand.
