So I recently returned to Sanctuary after a long-ish period around Diamond city, and I noticed a pretty annoying visual bug that starts at Red Rocket and continues until about the protagonist's old house in Sanctuary. Basically the roof of the station is missing huge chunks of it's textures, there is missing terrain next to the road, and once you get into Sanctuary itself, the road just disappears until the protagonist's house (though it must physically still be there because my character just floats above the dirt). Not only that but the walls of some of the houses have disappeared (completely in this case. I can walk through where they should be) and when I stand inside what should be the house, a whole lot more disappears from my screen, including all of the nearby terrain and buildings.
The only mods I can think of being the cause of this are ones that affect Sanctuary and settlements more generally. Those being in my case Sim Settlements 2 and it's addons, repairable sanctuary, and higher settlement budget. I have tried disabling each of these and starting a new game, and each time the problem is still there. The only notable change that occurred was when I disabled Repairable Sanctuary and loaded my main save and the bridge was gone, but I expected that. I've reinstalled the game and validated my files and none of it is making any difference. Any suggestions would be welcome.
I did take screenshots but apparently they're too big to upload. 250kb is a ridiculous size limit.
