The issue is, as far as I am concerned, solved; I've deactivated the plugin (Wyrmstooth, not Dragonborn - part of the original issue is my purpose replaying Skyrim was to play Dragonborn and would not deactivate it), and having solved the issue on my free day spent longer playing than I care to lose by reverting to an old save for extra safety's sake. And I had thought that the load order I exported from NMM had been while Dragonborn and its Unofficial Patch were still active - it must not have been. That makes a lot more sense. BOSS log is pretty standard. Everything is cleared up to my satisfaction, but if you're curious (it may be worth understanding the conflict between Wyrmstooth and Dragonborn) I will still post it. Same goes for complete system specs (laptop, and it's an old machine - Skyrim capable but it isn't pretty on paper (actual gameplay is fine though FPS isn't always perfect)). I have made no modifications to the .ini files that I can recall. No texture/mesh replacers, and I do not believe that I had uninstalled any mods - certainly not immediately prior to the issue, and if memory serves, not at all. Thank you for your help, and I'd be happy to satisfy your curiosity with further information, but after disabling Wyrmstooth, the issues have resolved themselves and no others have arisen in their place.

SOLVED. Should've solved this sooner if not for my own inattentiveness. More thorough troubleshooting (after realizing that a lot of my initial impressions were wildly incorrect; for example, the whole of Falkreath hold was not affected, only some regions - both interior and exterior - and the area around Ivarstead was also affected) suggests that it was caused by some conflict between the Wyrmstooth quest mod and the Dragonborn DLC - disabling either corrected the issue. With Wyrmstooth gone, the issue is solved.

I would greatly appreciate it if someone could put together a simple mod providing unenchanted clothing versions (for use with the perk Mage Armor) of the Vampire Boots, Gloves, and the three (black, grey, and red) Armor types uploaded to the Nexus. Just five or ten of each item in a box somewhere, or even just console access to the items. Thank you.
