‘Special Permissions’ is also unchecked on my PC.
It should “just work” for appdata saving - I did a little googling and found mention reminded me: The creation of the SaveGame (where it checks if one exists and creates one if it doesn’t) should probably be executed in your ‘GameMode’ class. (be sure to set game mode in project settings after creating it) - I believe this is best practice and would help solve any ‘order of operations/execution’ sort of problems.
Cheers
