yugutou Thanks for posting the video! I was able to reproduce the decimal point frame problem, but when I exported Spineboy from 4.1 and imported it into 4.1, I got the same results. So I think this is not a bug in the 4.3 export function, but in the 4.1 import function. Unfortunately, as Nate answered, we cannot fix this problem because we cannot fix bugs in older versions.
I wasn't sure how to reproduce issue 2 in your first post, have you found a way to reproduce this?
