Tested a bit too, but changing the timestamp doesn't really help at all. Yesterday I used a specific number of your texture-changing *paks, and somehow everything worked. Just started the game again, and everything is messed or not loaded at all

Tried re-packing etc. as, also to put them all together ..
What helped - at least for now - was to unpack every file of you and simply put them in "...\Steam\SteamApps\common\Divinity - Original Sin\Data\Public\Main\Assets\.."
Sarongs are gone, weird texture behaviour = gone, and every char has the modified texture..hopefully this will lasts for a bit :P
