A while back I made it so that (as example names) World A and World B had synced inventories. Thus, if I wanted something from World B I just needed to warp there and back with the thing I needed. But I've totally forgotten how I did it now, and I want World B to sync up with World C now. Any help? The only plugins I can imagine being linked to this would be Essentials and MVCore, both of which I have. I will try to provide any help I can from my side, when possible. If it helps, my server is running on 1.11.2, and I don't have any purely-inventory-related plugins like Multiverse-Inventory or anything like that on it.
