i have an issue, i built items, duplicated and renamed the master folder to share it, but it doesn't work for people,
apparently it's because of a relative paths to reference files.
i called my pack "2020DecoBlock", i did it with blender, and put .png icon with Item editor
i duplicated it then renamed my pack before the release to "Evolutive",
and it doesn't work since this new rename
the pack is findable here > http://www.maniapark.com/ressource.php?id=4521
and one of message that i recieved from Item Exchange >

after downloaded it, if you rename "Evolutive" to "2020DecoBlock", you will see that it will work
