Inventory System Save System - One Object Spawns on Play After Being Destroyed

I’ve done this, but the error hasn’t resolved. Here’s the code.

Blueprint Runtime Error: "Accessed None trying to read property Inventory System". Node:  Set InventoryContent Graph:  Save All Data Function:  Save All Data Blueprint:  BP_GameInstance
Blueprint Runtime Error: "Accessed None trying to read property Inventory System". Node:  Set ObjectData Graph:  Save All Data Function:  Save All Data Blueprint:  BP_GameInstance

I’m having issues with the clear actor data, assumedly because actor data doesn’t have anything in it to clear, but I’m not sure how to check that so the error is eliminated.

It looks like the 'load game from slot’s class is null. That’s probably why the cast is failing here. The savegame does exist and it should be of the right class, I cast and set everything.
