Okay, from the beginning:
I set up my world state in the Keep, loaded it up, and started playing. A few hours in I realized my character looked really bad outside of the CC, and decided to restart. However, when I tried to make a new character, my previously loaded world state wouldn't import. I received a prompt to use the default world state.
I exported it again, and it still didn't work, so I went and rebuilt the world state from scratch. I loaded this one up and it worked, so I tried to make a new character. I was planning to keep making characters and trying different appearances until I got one that looked good outside of the CC. I didn't like the first attempt, so I went back, and once again my world state refused to import.
