Can confirm it is fixed in 25w41a, because visibility of vignette effects, including world border warning, are now controlled by the “Show Vignette” setting, thus making general graphics settings not affect it.
Also affects Skeleton Horses, both likely use the same AI functions
Can confirm, change is also inconsistent with Skeleton Horses, which do not despawn on Peaceful Difficulty
Not a bug per se, the issue is caused simply because non-default languages don’t yet have translations for brand new content. May be worth to mention it on Crowdin, but likely Mojang staff is pre-emptively aware, and will make the translations when it is relevant.
Can confirm from game recipe data files:
Nautilus Armor are absent from [material]_nugget_from_blasting.json
files, but are present in [material]_nugget_from_smelting.json
files, which causes them to be smeltable in normal Furnaces, but not Blast Furnaces
