Hey Ouka~
I was just trying to look into this as well, because I wanted to see if I could add more markings. So I tested this. I added more, and they still looped over to default markings, like you said. So I took count of all the markings that DID show. It was 280.
BUT.. I did that for the [FHead] markings. On a hunch, I did the same thing for [FBody]. What was odd, is that the end limit for those markings was 255 before they started looping back. This is very odd, and I'm hoping someone will see this and it will be helpful. xD..
