In no particular order:
1. Small error in Gray's dialogue. When he tells the player to go meet dr. Moraescou, he says to take the ladder instead of stairs (given that there are no ladders in the tower).
-ohkay, fixing.
3. Killing the Jackal warehouse vendor guy effectively removed any possibility of trading in that spot. I chose Carl as a replacement, the neurotic guy agreed, quest has concluded, but Carl is still where he was, without even as much as a dialogue change.
-there are merchants at the front door too. But I don't know if it's a bug or not.
4. Every time I get Douglas to repeat who he really is I get the notification of a new entry in my personal diary, even though nothing new was (re)added.
-that's a bug alright
5. How do I find the Lumeniers' hq? Unless it's the Renessance, then back to point 2. Can't even find the area on the map they're supposedly patrolling, the guy that gives me that info didn't have anything else to add.
-nope. Lumeniers are there to tease you. No base, no backstory except the bits you get. Devs promise they will have a major role in the sequel. The patrols and the occasional outpost can be found between the oasis and tower.
6. Little lame that no one reacts to power armor, neither the regular folk nor the Olympus personnel (given that I'm clearly a guardian now, not a mere seeker. I guess F2 really spoiled me here, I liked when npcs so clearly reacted to that.
-the personnel are used to it, I suppose)
7. Dialogue about dealing with Emily in Livos is repeatable. I even got the positive karma and the title after finishing the quest without choosing to lead the vault, then choosing it afterwards.
-bug, noted
8. What are the Graves for? One of them has some small indentations in it for something but I didn't figure out what. The graves themselves have seemingly inconsenquential junk in them.
-you should really watch firefly. Seriously, strongly recommend.
9. After translating the book's title, the lone wanderer disappears but his location stays. Is there supposed to be a follow up to this?
-it is a callback to the "book of ely".
10. Killing Loudmouth and Billy changes nothing. Loudmouth's death is barely noticed, while no one cares about Billy. Other two big wigs have no change in dialogue whatsoever.
-uhhhhh
There's a ladder in Loudmouth's room, which I didn't notice either. That aside, I share the phone verification sentiment.
EDIT: I completely forgot to thank you, Keyboard Gecko, for the job well done. I was gazing wistfully at this mod every now and then for years. After I finally forgot about it, the news reached me last week, about the translation being already complete no less. Already finished the main quest today, the whole thing was really enjoyable.
-you're welcome! Credits go to @Rainman and @Ursa for all the work.
