in the folder Additional Support Files 2\Data\Meshes\clutter\potions\morro\m, there are some potions.
They turn up purple for me.
I can't seem to find the textures to go with these potions anywhere, I looked in Additional Support Files 2, Eloth Misc Items & Ingredients, Additional Support Files 1, Morroblivon Complete Installation Part 2, Morroblivon Complete Installation Part 3, Morroblivon Complete Installation Part 1.
the potions nifs are
MiscUPotionUBargainU01
MiscUPotionUCheapU01
MiscUPotionUExclusiveU01
MiscUPotionUFreshU01
MiscUPotionUQualityU01
MiscUPotionUStandardU01
missing textures:
textures\clutter\potions\morro\m\kupotionubargainu01.dds
textures\clutter\potions\morro\m\KUPotionUBargainUSquirt.dds
textures\clutter\potions\morro\m\KUPotionUCheapUSquirt.dds
Textures\clutter\morro\m\KUExclusiveU01.dds
Textures\clutter\morro\m\KUExclusiveUInU01.dds
Textures\clutter\morro\m\KUPotionUFreshU01.dds
Textures\clutter\morro\m\KUQualityU01.dds
Textures\clutter\morro\o\KUQualityUInside.dds
I'm not using any texture mods.
an older version of the potions do exist in the Morroblivon Complete Installation Part 1, but those are original looking potions with original looking textures. So they get overwritten by the ones in Additional Support Files 2 which require textures I can't find.

Same here. I didn't say anything because I could find only one other report of this, and she eventually got it to work; hence I've been assuming I was doing something wrong (and still am, really). If it were a bug I'd expect to see lots of complaints, as potions are all over the place...
That said, I can't understand her fix. It looks to me like she's saying fresh extraction of the second support files pack should do the job, but it doesn't, and neither does the first support nor the three "complete install" packs contain the files you've listed.
Thus far I haven't used WyreBash or anything like that, I just extract archives straight into my game folder and use OBMM to sort out the load order. I'm not using a separate "Misc Item Replacer", nor am I using Eloth's Visual Overhaul.
