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

so an example of where to use it is common getter functions, so if GetPlayerInventory is something along the lines of GetPlayerPawn(0)->GetComponentByClass etc you can put that in a function library and reuse it. this allows you to handle the IsValid checks with error checking too

you mean the inventory component is empty? as in lost all its functions etc? possibly you made a duplicate by mistake?
