firstly thanks for the fast answer.
i changed a bit the nodes.
if i start the game the first time, it does not load or save.
if i finished a round it creates a save game object
If i reopen the complete game it load game from slot, if i allready played a round
everything fine!
But if i have to save the game the second time i really dont know if it works. i think this is what i can solve by myself maybe.
the only big problem is that i have to know how i can remove the errors what appear every time i start the game. it doesnt deppends when i come to the menu
