Getting a funny line in my warnings.txt and hoping someone will recognize it. I'm not sure if this is all one warning, or if two lines keep getting combined, but the weird part is that I can SEE that the flask file IS actually there where it's supposed to be, and is named with a zero and not capital O (my first guess about what was wrong). My second guess (that it was \M\ instead of \m\ directory) didn't pan out either. Any ideas?

TES3Stream Warning: Model "Meshes\m\Misc_flask_03.NIF" tex not found "tx_g_glass03.dds"!
Texture Load Error!: tx_g_glass03.dds

There are other "Not able to find Ankle / Knee / Upper Leg part" listed as well, but since those are internal to other files I cannot easily go looking

it may be that Misc_flask_03.NIF or tx_g_glass03.dds is corrupt you could search your mods and replace it. the "Not able to find Ankle / Knee / Upper Leg part" is a BB thing being that they don't use all the body parts that the stock bodies do.

This warning is specifically about the texture "tx_g_glass03.dds" not being found. If this is from a mod you might want to have a look at the readme to verify where the texture should go. Usually textures go directly into Morrowind> Data Files> Textures.
