After finally crafting, pistols/smgs do not get the precision bonus from laser sights at all, whether bought/found/made by player, but that is so far the only weapon mod standing out as non-functional. The two new muzzle break and barrel compensator seem to be working just fine.
6. Free Drones quest "Visit Junkyard hideout" seems to be bugged. No journal entry and door in Junkyard is closed. (but Trenton gave me this assignment)
I experienced that before the update actually and found a way to get it to work too; was related to my responses to the two leader guys in the dialog as they are explaining that particular quest to you. Positive responses kinda made it buggy and not trigger but being neutral/negative got it to trigger, took me several tries but eventually worked as should.
Noticed a similar problem with Lenox Pierce (SGS guy who lost his brother) dialog when you first accept the quest from him and you then ask for info about his brother right after, and the dialog window just disappears like you said goodbye instead, but otherwise was able to finish the quest normally later, after you did more legwork in the quest progress.
Oh yeah, a little weirdness, after reloading a game in the lower underrail near Lurker base tunnels, wire gates I had opened were shut after reload, but normal doors were still open properly.
