How my character looked....

I do use a lot of mods, but this is what I did to isolate the issue and determine that the base game has changed:
I just downloaded the http://skyrim.nexusmods.com/downloads/file.php?id=3563 optional warpaint replacement files so I could check their file structure (to see what files I should be looking for, since I didn't know what controlled warpaint). Since it makes all of the warpaint on females look like lace, it was very easy to check ingame whether it was working or not -- it did. Theirs sends stuff to Textures\actors\character\character assets\tintmasks. I have nothing there in my game (no character assets folder period), so this has to be something that last update to the game itself did.
I also just looked at all the human races/elves, and the warpaint I originally used isn't an option for any of them. It seems like a good number of the ones that were standard across all the races have changed for me. The first one, for instance, is that messy bit around the eyes that Vilkas and Farkas have, except it's on my girls.
