After changing about 20 items on my character, the visual feedback no longer updates to show me what I've changed, and I have a constant spinning loading circle. I am running it on highest quality settings with 2.0x resolution scaling. Reset Set, and Random don't fix the problem and there's no way to get back out to fix it, you have to either save the charachter and continue as is, or End Task.
Second time round I couldn't reproduce, and everything loaded fine.
