Thanks for help bro.
So i was wasting time when created User Name and User Index in DatacenterGame actor ?
In case i’m not using slot name and index, how can Does Save Game Exits node checking save game exits ? It’s checking in MyGameMode or in DatacenterGame actor ?
I tried removed all slot name and slot index as your example, but when gameplay running it showing up another bug here :
i let it print variable at output Set LastLevel ( which i’m using to save new variable to DatacenterGame ) but it’s warning “accessed none trying to read …”
i was check input pin of Set LastLevel and it showing normal with variable going into Set LastLevel.
