it was not to major of a bug, in fact it probably does not matter, but i kinda found it annoying, during the main quest when you are escaping the jefferson memorial, you can hand a guy a gun, and one of the options is .32 pistol, his actual diologue does not mention the gun, just the word choice of you offering it to him, so if you have time and remember to fix that it would be cool.
im pretty sure this is already on there, but sound really screws up inside the pentagon, and im pretty sure it has something to do with side conversations and power armor, i think i heard it in raven rock also but i am not sure,
also i hope to help you fix some more bugs as i am a huge fan of this mod, hopefully next time it is more major of an issue, anyway the subway looks very proffessional keep up the good work, if i find anything else i will post it here.
the gun nut perk says it is going to increase the small guns skill
