I chose to talk Audra down in the first companion quest and leave the transport untouched, but the quest reactivity acted like I had blown up the transport and the rest of the cell members were culled by the Protectorate. I'm not sure if this was triggered because I killed the guards outside the transport before rescuing her or not, but that was not mentioned as having potential consequences. Likewise, on a previous playthrough, I had killed the guards and helped her blow up the transport and that did not cause the cell to be culled.

It's really designed in a way that wants you to play through multiple times, which is fine. It just would've been nice to have a more explicit warning about it. Thankfully, I got where they were going with it before I left the first planet, so I was able to salvage the run before assigning too many points outside what I was focusing.

Additionally, the blue forcefield prop/environment object and the energy tether effect from one of the Companions' abilities causes massive framerate drops.

Just wanted to throw some of my thoughts out there from my playthrough so far (I'm Lv30 and about halfway through the second planet of the second pair). Encounters that force you out of stealth and the game having no way to drop back into stealth (outside of maybe smoke grenades) feels bad; it wasn't fun on the initial Deus Ex: Human Revolution release and it's still not fun here. Late-game guns appear not to have silencer attachments for whatever reason, which means you're stuck using the earlier marksman rifles and sniper rifles unless you want to swap to Heavy Revolver (which is the only non-unique weapon I've found late game that has a silencer attachment). Companions are largely useless on Very Hard without Leadership scaling even when max upgraded. Not being able to customize their armor/weapons outside of the two upgrade kits feels lacking. The High Security Lockboxes were fun to hunt around for in the first two zones, but they are virtually non-existent past those areas (I think I've found one since hitting the game's mid-point quest, despite combing the entire zones). Not being able to be successful in conversations outside of Speech checks feels bad. It would be nice if there had been alternate ways to reach "good" solutions without just putting points into a stat, as even the "additional" information that you can find from exploration often still requires Speech or Leadership checks after bringing them up in conversation. However, I understand having some outcomes/rewards be Speech-specific, as the stat would otherwise feel less useful. Lockpicking, in particular, feels unrewarding as a lot of the loot from locked chests is just bits and random junk (which feels like a regression in exploration after the all the meaningful loot scattered about in Avowed). Lack of stat points means (especially in Very Hard) that you must heavily specialize into 2-3 skills. Having a handful of extra points (either tied to exploration or quest rewards) would be nice so that you could pick up additional utility.

Looks like this can be resolved by quicksaving at the top of the elevator and finishing the entire encounter in one go. If you load a save after having entered the room, one of the turrets in the back will sometimes not spawn in and breaks the quest.

This companion quest fails to update if you have to resolve it violently because killing the junior arbiter does not update the quest (the marker stays above her body and the quest state remains the same).

It's definitely bugged. If you kill the witch when she's in animal form, she doesn't drop the grimoire. I think there's also an issue with the Lich, but I don't know what it is exactly, since I was able to obtain his. Other people have reported it as an issue.

Apparently, there is a bug that causes both the Lich and the Witch (Bipara) not to drop the item. For the witch, it's associated with killing her when she's in animal form. No way to get them without console commands if you don't have an earlier save, unfortunately. I can't complete it either due to the witch bug.
