Creating a new save game that holds a array of S_Item and set it to the current inventory. Save this save game object to a slot.
Load Inventory
Replace the “Init Component” from the inventory with “SERVER // Init Component and Load Inventory”. The inventory is loaded from a save game slot.
The "IsLocallyControlled" branch will ensure the clients version of the savegame is used to initilize the inventory.
If you want to only load save games from the server you should make "SERVER // Init Component and Load Inventory" not replicated and add a "isServer" branch into it.
