[VixikHD]

I have submitted pull request for ItemCase plugin (it is outdated, plugin does not work with latest api without the pull request)

• Link to poggit release: https://poggit.pmmp.io/p/itemcase
• Part of the plugin which is outdated: https://github.com/poggit-orphanage/ItemCase/blob/master/src/aliuly/itemcasepe/Main.php#L165 (Packet requests itemstackwraper instead of Item)
• Pull request: https://github.com/poggit-orphanage/ItemCase/pull/8
