If you have a custom Game Instance:
Go into your Game Instance blueprint → Class Settings, and implement “BPI_Saving”.
Next, copy the events inside GI_CurrencyPal to your custom Game Instance.
Create the missing variable “CurrencyData” (map of GUID | Int).
If you do not have a custom Game Instance:
Go to Project Settings → Maps & Modes, and set the Game Instance to be GI_CurrencyPal.
