Traveler's Backpack suport pls

[Nikix03]

I appreciate your application as it saves the inventory information of my users on the server. However, some of my users complain that they lose their backpacks when switching from one server to another via BungeeCord or a similar tool. It would be very helpful if this issue could be addressed. Thank you very much.
