As an aside for anyone unfamiliar: Arthmoor's unofficial patches go beyond just fixing bugs, they also implement retarded changes. Three notable examples in Skyrim that stuck out to me:
1. Re-implementing a placeholder line of dialogue for the first dragon you kill that sounds
awful.
2. When you become Arch-mage, the mod gives you two sets of robes (hood and hoodless) and makes it so you can't wear circlets or masks with either of them. This is because they have a 'hood' (it's attached to the robes, not a separate armour piece) and you can't wear those things with hoods ordinarily, so putting a circlet on your head forces you to remove the entire robe. This basically makes the robes a waste of space.
3. Any and all exploits (Smithing xp, potion crafting) were also culled.
Here's a link to some redditors discussing more of these changes.
I think he implements these shitty little touches as a quasi-form of DRM, since you could fork it, claim it's a bugfix mod of your own design, and then he'd autistically look for the little traces of pointlessness that were trademarks of his mod to determine whether or not you were lying.
