If disableclothingfilter is on, then the game will start with the Custom Clothing Filter on. This is a safety measure: If you don't turn it on, the game will pretty much lock up and die as it tries to load EVERYTHING IN THE UNIVERSE all at once while you fumble for the category you want to reach.
I've enabled this option in the config, but it doesn't seem to be working, CAS immediately loads all content (running the latest Awesomemod from 18/11).
