It seems the Advent Children Cloud sprite is too big to replace the original Cloud sprite in shishi's sprite manager. I honestly don't mind not being able to get it to work but if anyone knows how to make it work let me know.
try these, they didnt give me the error, make sure and use shishi .352, it's what I used.
I can't figure out how to save the changes. Do you know where to save to?
You don't. It's saved when you import.
