Hello, hope everyone's doing well,
I'm trying to duplicate skins and use the rename attachments function when duplicating. It has worked no problem for many other skins in the past, but it's never certain when it will or will not work. I think it might be because of previously renamed placeholders, but I don't know what I need to name a placeholder to fix the problem to make this function work. The folder structure and case-sensitive file naming has been quadruple checked and should otherwise work. The renaming simply does not happen.

After reading through this post and the linked github entry, I'm still very confused as to what I need to do to solve this issue. Any clarification would be appreciated.
