Thank you for your help! The shelves are now being saved and loaded properly. Nevertheless, I’ve tried to use the same method in order to save the player’s inventory but without any success…
The player’s inventory is a custom component I’ve created and added to the player’s actor blueprint class. The component contains a map variable I’m trying to save. The player’s actor seems to be saving and loading properly though, because the gold amount the player has is being saved and loaded successfully.
