The way I say it there are only two good options: I had to write an awful lot of code to fix all of this. The appearance has to be continuously maintained. It may sound weird, but you cannot simply set your character's appearance at some point and be done with it. Oh, and then there's this other amusing little quirk: When you change your character's appearance during combat, the currently selected style won't work anymore. And don't even get me started on the problems my own gem armors may cause when you fiddle with the appearance (or the texture).
Depending on which model(s) you've picked transforming back into your regular appearance might fail. Another issue might be transformation styles. When you enter the spirit world, the game overwrites your appearance.
Which one should the game pick, if there's more than seven? Yes, and there's the spirit world. Each of these cutscenes exists in seven versions - one for each character in players.2a. I counted 13 of those throughout the entire game. When you add more than seven characters to the players.2da you're asking for trouble.
It's in my Treadwatch, but 'Threads' is 0.
Sorry, for the very late reply! I did not notice your post until now.
