What is the function of the Save Game option in the Variables section of the Blueprint?

I’ve found that checking the “Save Game” option in the variables section of the blueprint does nothing to help my game saves. I still have to manually save this variable to the game save file and manually assign its value when loading the save. So what exactly is the purpose of this option?

its a property flag, probably only used in c++ so i can basically get all variables with SaveGame and serialize those.

if you’re game is simple you can ignore it but for complex saves i’d highly recommend using c++
