This datapack synchronized every player's inventory. Whenever a player obtains or loses an item, everyone also obtains or loses it.
That's said, if a player died, everyone's inventory will be cleared instantly.
Use /function si:install to activate it, and use /function si:uninstall to deactivate.
This datapack is inspired by this video.
